Sometimes, a sequel to a video game is completely different from the original; perhaps the designers got a little overexcited about creating new things.
Other times, however, you get just the opposite: Essentially, extra levels for the original game. Either it's the same engine, or the feel is identical, or what have you; but nevertheless, the player feels slightly ripped off. Any way you cut it, you're paying full price for an Expansion Pack.
Some gamers enjoy mission pack sequels when they are obviously such, because then they know exactly what they're getting into, and sometimes extra content for a fun game is a good thing. Other gamers don't trust their favorite companies to innovate, and would rather they stick to what they're demonstrably good at.
Thanks to the general contrariness of many gamers, not producing this kind of sequel when expected to can result in They Changed It, Now It Sucks. Critics, on the other hand, tend to be Sequelphobic. This trope provides exclamations of It's The Same Now It Sucks.
To compensate for the lack of new play mechanics, a Mission Pack Sequel may feature harder levels than the original game, with more and/or tougher enemies.
Some old games did this in a manner similar to Divided for Publication, when ported to a system which couldn't fit all the stages onto one cartridge. Also, older consoles usually did not allow for actualexpansion packs due to hardware limitations, leaving Mission Pack Sequels as the only way for developers to add new content to an existing console game.
Remember that just being part of a series doesn't make a game an example of this. Having a similar game system is part of the definition of being a series; a game only qualifies as a Mission Pack Sequel if the sequel adds almost nothing in the way of innovation or new features.
An installment that embraces this may be marketed as a "stand-alone expansion" instead of a full sequel, which usually means a lower retail price.
If it looks like a Mission Pack Sequel, but isn't a sequel, then it's probably a Gaiden Game.

Besides the license involved, all the Lego Adaptation Games pretty much fall into this. There's been some interface changes throughout them, but they remain similar enough that you could buy one based on which of the licenses you like best and not be missing out on anything. On the other hand, they're all a damn good time.
The Ninja Gaiden trilogy for the NES were all developed on the same engine, although the sequels made some subtle changes to the original game system and each installment had at least one exclusive power-up (namely the somersault attack in the original, the red shadow clones in II, and the sword extension in III). Oddly enough, III is the only game in the trilogy that doesn't have the pseudo isometric perspective as the first two games.
The Tomb Raider series on the PlayStation used the same game engine for five games, but each game had better graphics than the previous game, new mechanics such as sprinting and monkey swinging. By The Last Revelation, the graphics haven't improved a lot and the game mechanics remained generally unchanged, save for one or two new abilities. By Chronicles, the game literally recycles a lot of the textures and sound effects, along with the game mechanics from the last game so nothing ever changed.
Blaster Master: Enemy Below for the Game Boy Color was similar to the original NES game, reusing graphics and music (albeit with different instruments) from the first game. However, the maps, weapons and bosses are entirely new.
Cheetahmen II reuses a lot of elements from the original Cheetahmen on the Action 52 NES cartridge, including the catchy music, the numerous physics glitches and the erroneous level numbering. In fact, the last two levels of Cheetahmen II (normally unreachable due to a Game-Breaking Bug) are copied wholesale from Cheetahmen.
Beat Em Up
The arcade version of Double Dragon II: The Revenge was essentially a heavily modified version of the first game. The biggest change was in the game's controls, which used directional-based attack buttons instead of the punch and kick buttons from the first game. The level layouts were also changed with different enemy placement and new traps, most of the returning enemy character were given a few new attacks in addition to their new looks, some of the weapons have different properties and all of the stages have a new end-boss.
On the other hand, the NES version of Double Dragon II used a completely different game system from the first one.
Final Fight 2 is essentially the SNES port of the first game with nation-themed stages (Hong Kong, France, Holland, England, Italy and Japan). It justifies itself by adding a 2-player co-op mode, a feature from the arcade version that was missing from the SNES port, as well as having a full 3-character roster in one cartridge (as opposed to having a second version with a character replaced, as was the case with Final Fight Guy). The sequel even brought back Rolento, who was the only boss character from the first game missing in the SNES port.
The Fast and the Furious arcade game from Raw Thrills received a Mission Pack Sequel in the form of Fast and the Furious: DRIFT, which added some new Japan-themed tracks, improved the graphics, and added in some new cars on top of some returning cars. The tracks from the original game all returned, and gameplay was mostly the same.
One can easily argue that the various San Francisco Rush arcade games are Mission Pack Sequels of the original; while the tracks and graphics have changed, the fundamental gameplay and emphasis on real-world physics does not. Averted with the home console versions, which add additional modes that don't involve racing around a track.
Similarly, the Cruis'n USA series (Cruis'n World, Cruis'n Exotica, and the Spiritual SequelCalifornia Speed) is made of Mission Pack Sequels to the first game.
Ridge Racer 2 for the PSP is a very blatant example: It's exactly the same game as the first one, with a few additional tracks and a couple of (mostly irrelevant) playing modes. Nothing else is different. Yet it was sold at full price (and with no indication of this in the covers).
Crazy Taxi's various sequels were strictly alterations of the setting and characters, although they also introduced a jump button.
The various Street Fighter sequels, after the first version of Street Fighter II, tended to be Mission Pack Sequels of the highest degree. At least the ones that were Mission Pack Sequels were labeled as such.
According to those who worked on both games, Tekken 2 was what the first Tekken would have been like if they had had more time to work on it. The character roster keeps all the same characters from the original and adds several more (renaming Jack to Jack-2 to fit in with his story). It also uses the same music from the first game for several levels. However, it is a new game in that all the returning characters are redrawn with better graphics, far more moves are added to distinguish boss characters from main characters, and the Playstation version had many new modes added whereas the first game just had Arcade, Vs and Options.
First Person Shooter
The second Brothers in Arms game, Earned In Blood. The first half are different takes on the same mission as the first game, or missions that occured in-between. The rest of the game is completely new.
Doom II: Hell on Earth is a good example of this trope being done right. The game engine is identical, it plays the same and there's only one new weapon and seven new enemies, one of which is a Palette Swap (compare to the original game's eight normal monsters and two bosses). The main attraction is the 32 new levels featuring sublime design, which is one of the reasons many Doom fans consider Doom II the best game in the series.
In turn, Final Doom was a one of these to Doom II, but only contained two sets of new levels - which makes sense, considering one of the sets was intended to just be a Game Mod.
Marathon Infinity's Blood Tides of Lh'owon was basically just M2 with more levels. As the title indicates, however, Infinity's main features were really Anvil and Forge.
The first game also had the 20/10 Level Pack, which would introduce 20 new single player levels, 10 new multiplayer maps, and the shotgun. The Level Pack was never actually released as intended, though; it added so much that it was released as Marathon 2: Durandal.
Left 4 Dead, meet Left 4 Dead 2. New characters, new levels, but same gameplay. To Valve's credit they added chainsaws, frying pans, and an updated Director which can change levels around and trigger weather effects. That still didn't stop the Internet CounterattackFlame War.
Rumor had it that number two is based off of content that at one point was going to be (free) DLC for Left 4 Dead one, making this a literal Mission Pack Sequel. Valve eventually stated that L4D2 was going to be DLC, but that the amount of work that went into it, including graphic upgrades, voice-acting, new weapons, and more, merited a full-release, albeit the console version retailed at 2/3rds the cost of a typical game.
Halo 3: ODST was originally announced as a downloadable add-on for Halo 3, but it ended up becoming a whole new game. However, all it really does is add a new single-player campaign, a new game mode, and a few new multiplayer maps. The actual multiplayer gameplay is identical to Halo 3's. So far the biggest complaint about ODST has been its surprising brevity (you can finish the game in about 7 hours) contrasted to its full $60 price tag.
BioShock 2 could be said to be one, as the engine and basic setting are the same, and it's more of a side-story than a full sequel to the original game. It was not made by the team who made the first game, and included a multiplayer mode.
Medal of Honor: Underground is a mission pack prequel, using the same engine as the original with a few slight gameplay alterations.
Unreal Tournament was originally going to be a second, multiplayer-focused expansion pack to Unreal; however, with just how big the new game was becoming, the developers split it off into an entirely new game. They still run on the same engine, though, plus UT still has most of the original's assets included, which has lead to mods recombining the two.
And then Unreal Tournament 2004 to 2003 - essentially the exact same game, except with more playable models, the addition of vehicles, new weapons, new models for existing weapons (with the option to choose which model to use), new maps, and new game modes, including the return of Assault mode. Epic themselves consider UT2004 to be what UT2003 should have been, and even gave out rebates for players who traded in UT2003 for it when it was first released.
The first game's expansion deserves a mention like the Quake expansions below, as its official name was "Unreal Mission Pack I: Return to Na Pali".
While Quake and Quake II are very different games in terms of technology and story, they deserve an honorable mention because the expansion packs (two for each game) were actually labeled Mission Packs and offered additional single player campaigns in each one with some new weapons and enemies.
Jedi Academy is the only game in the Dark Forces Saganot based on an entirely different engine than the previous game (excluding Mysteries of the Sith, which was an actual expansion for Dark Forces II). As such, it looks and plays near-exactly like Jedi Outcast does. The main draw is the customization options for the new player character and his/her lightsaber and Force powers, compared to the static saber and power growth in Jedi Outcast.
Serious Sam: The Second Encounter is an interesting case. The game itself followed this trope—same engine, additional weapons, enemies and environments—as well as a greater abundance of lame jokes from the companion AI. Yet despite being called The Second Encounter, the next game in the series, which did contain major changes to the style, gameplay and atmosphere, was called Serious Sam II, causing some confusion with the other game whose subtitle suggested the same thing. It can be confusing when looking for information regarding both installments, and it's easily to completely overlook one or the other for this very reason.
The HD editions of the original games takes this to its logical conclusion by way of the "Fusion" DLC/update, which adds all the content from the first game into the second to let people immediately jump from First Encounter's Egypt levels to Second Encounter's South America ones.
Ghost Recon started out the same way - the original game and its own expansions were all basically Rainbow Six in expansive outdoor environments and with more of a then-next-gen US military theme to the usable equipment. It eventually split off and became its own unique series with the cover-based Third-Person ShooterAdvanced Warfighter... until Rainbow Sixbegan taking cues from the console versions of Advanced Warfighter for the Vegas spinoffs.
To round it out was the video game adaptation of The Sum of All Fears, which was also basically Rainbow Six with the plot of an entirely different Tom Clancy novel-turned-film - though notably, the game putting you in the shoes of the FBI's Hostage Rescue Team makes it pretty close to the original plan for what became Rainbow Six.
Call of Duty is notorious for this. One of the biggest criticisms is that the multiplayer aspect doesn't change a whole lot between each installment, other than some new maps, reskinned/new guns, and reskinned characters. To add insult to injury, the DLC for Modern Warfare 2 allows you to play maps from Call of Duty 4 that look identical, but are running on the new engine. They have been trying to introduce new ideas to the multiplayer in later games (at least, the ones byTreyarch have), but the graphics are still on about the same level they've been since Call of Duty 2 - to the point that Modern Warfare 3 even uses the exact same HUD layout as MW2, with only updates to the text displayed over it for new game modes and weaponsnote not to mention reusing old assets at every chance they get - a German mortar model from CoD2 is still finding its way into every CoD since then, plus MW3's singleplayer mode reuses a ton of MW2 models for returning guns. This is really starting to bite the series with Call of Duty: Ghosts, which has on average scored and sold lower than Black Ops 2 (breaking the trend of every CoD breaking the previous one's sales records), in part because it refused to adapt any of the changes BO2 added and is seen by many as, in effect, Modern Warfare 4.
Crysis 3, unlike the jump from the first game to the second, had the HUD almost entirely unchanged. The nanosuit powers are the same too. In fact, a look at the game files shows that many of them are unchanged from Crysis 2, including the files for most weapons and enemies.
Many, many low-profile games have a Mission Pack Sequel, such as the Caesar III spin-offs.
Come to think of it, this is practically endemic to certain genres, like RPGs and Interactive Fiction games. However, as many times it is not - as the trope description says, merely using the same engine and assets does not mean it's a Mission Pack Sequel.
Hack And Slash
Warriors Orochi 2. While the rest of the Dynasty Warriors series just barely avoids this trope by using new character models and maps for each iteration, even if they all have the same story, Warriors Orochi 2 is literally a Mission Pack Sequel of the first Warriors Orochi with some new characters thrown in for good measure.
It turns out that Warriors Orochi 2 was, in fact, an expansion, whereas Warriors Orochi 3 - titled Musou Orochi 2 in Japan, is the true sequel. Thanks for the confusing name scheme, Koei!
The Armored Core games are notorious for doing this. Every game with a number at the end of it are brand new games, but every game with some kind of Word Salad Title is just a Mission Pack Sequel built on the numbered game's engine with a few minor additions or subtractions. This was how From Software managed to put out one Armored Core a year for a decade. Now that they've started making games for the PlayStation 3 and Xbox 360, they're putting more effort into individual games, hence why there was only one Mission Pack Sequel to Armored Core 4 and it's taken three years to go from it to Armored Core 5.
The Super Robot Wars series, albeit this merely in terms of overall concept, which is pretty identical in all incarnations (turn based strategy with big robots as units). Otherwise, the game engine has undergone revisions and the list of series and the plots vary from game to game.
All of the Mega Man NES games, and some of the Mega Man X games, as wellnote specifically, Mega Man X2 and X3 are this to the first one, and so are MMX5 and MMX6 to MMX4). The gameplay is so similar across each series that hackers have created speedruns of Mega Man X and X2 and Mega Man 3, 4, 5, and 6 by running several emulators on the same controller input.
All of the Mega Man Zero games, the two Mega Man ZX games, and the Battle Network and Star Force games could all be stuck together and nobody would notice (in fact, they did do so for the Zero series). Mega Man's bread and butter is Mission Pack Sequels.
The Japanese version of Super Mario Bros. 2 (aka The Lost Levels) was conceived when Miyamoto and his team were working the arcade version of Super Mario Bros. and redesigning the stages to make the difficulty more suitable for arcade play. They decided to create a new version of the game that only expert players could clear, which is why the original Famicom Disk version was released with the tag line "For Super Players". This is likely the reason why Nintendo of America choose to skip this one and localize an unrelated game Doki Doki Panic, as the American version of Super Mario Bros. 2, which turned out to be a better investment in retrospect.
New Super Luigi U is a straighter example. As a DLC for New Super Mario Bros U (and later a stand-alone game), it uses the same graphics and textures, though Luigi's controls are a little different from Mario's.
While not as blatant as the previous Mario examples, all New Super Mario Bros. games (other than the first one, of course) are Mission Sequel Packs.
Super Mario Galaxy 2 was originally intended to be an expansion of the original Super Mario Galaxy titled Super Mario Galaxy 1.5 but over time, new ideas were implemented and the release date was pushed back so more content could be made. It is still often seen as being this to the original because although most of the level design is not recycled, there are some new power ups and new ways to progress, the core physics engine and Mario's basic move controls were left untouched.
Sonic & Knuckles was actually a literal case of this: Sonic 3 was originally intended to be one long game, but, the developers, pressed for time, released only the first few levels of the game as Sonic 3, and then released the rest as Sonic & Knuckles six months later. But since the new Sonic & Knuckles cartridge could be locked on with a Sonic 3 cartridge, the two can be played together back-to-back as they were originally intended (and as a plus, joining Sonic & Knuckles with Sonic 2 lets you play the latter game with Knuckles as a player character to boot).
Tomb Raider 2 through 5 played the same as the original, with some graphics updates and a few new moves for Lara in each one.
Tomb Raider Underworld is a mission-pack sequel to Legend.
Jak 3 was very similar to Jak II, and felt more like Jak II 2 than a new sequel. This feeling is likely influenced by how vastly different Jak II was from its predecessor, Jak & Daxter. However, the game was still a huge game, with two giant open-world environments, a great story and the Light Jak powers added.
The arcade version of Super Contra was a sufficiently different creature from the original Contra. However the NES version, titled Super C, is basically the first NES game with all new stages. The 3D stages were replaced with overhead ones, and the Fire Gun was revamped: instead of shooting tiny fireballs that traveled in a corkscrew pattern, it now fired large ones which splits into four fragments when it hits an enemy.
Operation C for the Game Boy also qualifies. The play mechanics are ported over from Super C and the graphic style is also similar to the NES games, but the stages and bosses are all new.
Neo Contra is pretty much an overhead version of Contra: Shattered Soldier, using the same three-weapons setup, only this time you can choose your weapon configuration and the third weapon now acts as an anti-air attack which takes out airborne enemies.
Jet Set Willy II: The Final Frontier isn't just "more of the same"- a lot of it is almost exactly the same! Essentially it's an expanded rewrite that includes all the original screens plus some new ones. Originally designed as an Amstrad CPC port of the ZX Spectrum original, but making use of the extra memory, it was then ported back to the Spectrum.
Championship Lode Runner is like Lode Runner, but with more difficult levels. Irem adapted Lode Runner into four arcade games which differed from each other in little else but levels, including a number of original levels which were brought to the Famicom Disk System as Super Lode Runner and Super Lode Runner II.
Bonk's Revenge and Bonk 3 for the TurboGrafx-16. Revenge even reused alot of the music from Adventure.
Hudson's Adventure Island III was virtually copy-pasted from Adventure Island II in terms of graphics, music and play mechanics, with the only major changes being a new dinosaur buddy and a new weapon.
Miner 2049er Volume II for the Atari 2600 contained three stages from the original game that hadn't appeared in the 2600 version of Miner 2049er, which also had only three stages out of the original ten.
Yoshis Island DS often feels like one of these to the original. Although it feels less like an expansion pack and more like a commercially published ROM hack of the first game, with a significant amount of levels that feel like they took the basic structure of the original levels and bosses and merely tweaked them a bit.
Spyro: Enter the Dragonfly tried too hard to copy the feel of the games prior to it rather then create a new game. This, combined with its Obvious Beta status, meant the game didn't fair well with almost anyone.
Cybernoid II: The Revenge gave the player a different-looking ship with a few new weapons, but otherwise played exactly like the original Cybernoid.
The Katamari Damacy sequels. Fortunately, the original had enough enjoyably weird potential that it almost didn't matter.
Lemmings' first sequels, Xmas Lemmings and Oh No! More Lemmings, were this. Oh No! More Lemmings had 100 levels in four new tilesets, and with a much steeper learning curve if you hadn't played Lemmings already, but added nothing to the basic gameplay. A proper sequel, Lemmings 2: The Tribes, followed later; this added a slew of new skills.
Repton 3 was followed by three new scenarios using the same game engine: Around the World in 40 Screens, The Life of Repton, and Repton Thru Time.
Real Time Strategy
Cannon Fodder 2 is almost the same as the first game, but with different graphics and levels.
Homeworld: Cataclysm was apparently supposed to be an expansion pack to the original game, but ended up becoming a standalone when the developers started making gameplay and graphics engine changes. The results are still controversial. Controversy in the plotline aside, the more sequel-like sequel Homeworld 2 uses a control scheme much more similar to Cataclysm's than that of the first game.
Command & Conquer: Red Alert to the original Command & Conquer. Red Alert actually doesn't quite have the same engine, and the gameplay is slightly different, but in terms of overall appearance it practically looks just like its predecessor, especially once the original was ported to Red Alert's engine for the Win95 and console ports.
The two stand-alone expansion packs to Earth 2150: The Moon Project and Lost Souls. All they add are new mission and a few new units. That's it.
Haegemonia: Legions of Iron had a stand-alone expansion pack called The Solon Heritage. You'd think that, just based on the name, it would feature a storyline devoted to the titular Benevolent Precursors. Nope, the expansion doesn't even have a campaign. Instead, it add more maps, a few new ship types, a few buildings, a few techs, and the ability to make locked-down space stations move again. Needless to say, it was hated by fans of the original.
While Warlords Battlecry is a very different game from its predecessor, Warlords, the three games in the Battlecry series were essentially exactly the same but with new storylines and a few new playable races.
The Guitar Hero franchise has seen at least minimal improvements between major releases, such as an improved hammer-on and pull-off system, practice mode and co-operative gameplay between the first two Guitar Hero titles. Rocks the 80s, rushed out-the-door to meet the publishers' demands, featured only a modest facelift and new tracklist, and then the series was handed over to Neversoft and Activision...who started to apply this trope in full, starting with the release of Guitar Hero: Aerosmith. World Tour added full band gameplay (mostly to compete with Rock Band), and then even more band games were commissioned such as Guitar Hero: Metallica and Guitar Hero: Van Halen, not to mention the DS versions with the awkward "Guitar Grip" peripheral that plugged into the GBA slot. The entire franchise more or less reached its culmination of stagnation with Guitar Hero: Smash Hits, featuring nothing but remade versions of tracks from past Guitar Hero games, and Band Hero, with a new facelift and tracklist geared specifically towards the teenie bopper crowd with hard-hitting guitar classics such as "YMCA" and "Wannabe". Thankfully, they seem to have learned their lesson due to progressively weaker sales and reception, culminating in Van Halen flying completely under everyone's radar because the series had saturated the market so much, and most of the people who played the game got it for free with a code from Guitar Hero 5.
Rock Band 2 adds some interface tweaks and 84 new songs, but that's about it. Of course, it's hard to expect a whole lot more; it'd be kind of like attempting to innovate dodgeball or birthday parties. There is some room for improvement, though, especially as far as the instrument peripherals go, and the new peripherals packaged with Rock Band 2 are much better than the originals. And even then, if you're buying just the game and using your old instruments, 84 songs for $60 is a bargain by Rock Band's usual 1.99/song pricing.
Lego Rock Band and The Beatles: Rock Band fall into this too, though The Beatles version is very thematically different (if gameplay identical, although it did add three-part vocal harmonies). Rock Band Unplugged and the Nintendo DS version of Lego Rock Band are not considered one, being s Spiritual Successor to Amplitude instead.
Rock Band 3 seems to be circumventing this at long last, by introducing vocal harmonies from The Beatles: Rock Band, as well as a new keyboard peripheral and a more realistic 'Pro Mode'. Later on, Rock Band 3's price got officially dropped to around $30.
This is the case for damn near every Rhythm Game ever, especially the BEMANI franchise.
Dance Dance Revolution tried to subvert this with the Dance Dance Revolution Solo sub-series, which use single-player cabinets with up-left and up-right arrows in addition to the four familiar ones. It didn't last beyond DDR 4th Mix PLUS, though it made a comeback for DDR Konamix, which uses the 4th Mix engine despite being released in 2002, just before the release of the Japanese DDR MAX 2.
Additionally, DDR 3rd mix added the innovation of a tempo change, but it only occurred while there were no arrows on screen (in the song "Luv This Feeling"). DDR 4th Home/DDR 5th Arcade added the innovation of a tempo-freeze with the song "Healing Vision Angelic". DDRMAX added the innovation of a ton of new modifiers (most notably the speed modifiers), an Oni mode, and freeze arrows. The home versions also occasionally added new game play modes (such as the challenges in DD R4th, the mission modes in DDR Universe, etc.)
Role Playing Game
The Pokémon games. Every generation has had, at minimum, two alternate versions of one game that look and play exactly the same and a third rerelease that also looks and plays pretty much exactly the same but with a slightly altered storyline. Gens III and IV have also included remakes of past games, though these aren't quite this trope, as they take place in vastly different locations and commonly feature Pokemon that are extremely hard to get in the other games of their generation.
Pokemon Black and White Version 2 play this the straightest as it's essentially the usually third game in a generation except with an all new story. It's mechanics are more or less unchanged and the game has a few new features thrown in.
What all the Pokemon games recycle are 8-bit sound effect cries for the creatures, even though the games have advanced far enough in technology where such a thing wouldn't be needed.
Pokémon Stadium is a somewhat unique case - the original game, only released in Japan, had less than a third of the first-generation Pokémon available, with plans to add the others through a 64DD-based expansion disk. With the failure of the 64DD, however, they opted to just normally release a complete version of the game instead - Stadium 2 in Japan, localized elsewhere as simply Pokémon Stadium. When it came time for another sequel that added the hundred or so extra mons from Gen II, the Japanese released was named Pokémon Stadium Gold and Silver.
Might and Magic VI's engine was reused in Might & Magic VII and VIII; if you know how to play one of those games, you know how to play all three.
All the NES Dragon Quest sequels used the same engine, more or less. They made up for it by varying the way your party was set up. Specifically — DQI had no party at all, just a main character; DQII had a party of three set characters; DQIII had a set hero and up to three created generic characters; and DQIV had four "chapters" before the hero's storyline began, each focusing on one of the hero's eventual party members, each with their own parties (and party members).
The DS remakes of the "Zenithian Trilogy" also share an engine. DQIV has the "chapters" explained above, DQV includes the ability to recruit monsters, and the main selling point of DQVI is the job system.
Honestly, Dragon Quest never strays too far from its roots no matter what engine it uses. DQIX plays basically like III (and by extension all the other games in the series) but adds randomly-generated grottoes for Dungeon Crawling on top of the main game.
Fallout and Fallout 2 were built on almost exactly the same engine, and share all but a tiny number of assets. Then again, if you're playing Fallout for the interface, you're doing it wrong.
Fallout: New Vegas is an interesting case. The engine and nearly all of the assets from Fallout 3 are present, the skills and perks have been updated, the combat system improved, and crafting expanded as well as adding new enemy types. However, the world and quests are completely new while adding in content from the defunct Van Buren project and garnishing with a liberal helping of references to Fallout 2.
SSI's Gold Box games all shared the same engine and changed little in basic gameplay over the course of their history, but produced huge scenarios for players to explore.
Spiderweb Software's games, like the Exile/Avernum series, Nethergate, and the Geneforge series, present something of an odd case. The same engine and graphics are recycled for several games with few additions, but when Spiderweb does make a newer engine or better graphics, they are back-ported to all of Spiderweb's older games.
The Infinity Engine games released by Bioware and Black Isle between 1997-2002 (Baldur's Gate 1 and 2, Icewind Dale 1 and 2, and Planescape: Torment), all used the same engine and play style, with only cosmetic differences, graphic updates, and a few rules tweaks here and there. The games are compatible enough that there exist mods that package the entire Baldur's Gate saga in a single game, or to run Baldur's Gate II in the Icewind Dale II interface.
Digimon World: Dawn and Dusk for the Nintendo DS, when compared to the first Digimon World DS. Aside from changing up the numbers, adding new Mons, and creating new evolvution paths, it's pretty much the same game with almost the exact same graphics and everything. The same goes in turn for their unexported sequel, Digimon Story: Lost Evolution, to the point where practically no-one has bothered to put out adequately translated information on what's going on because of the sameness.
Both .hack// series mirror this trope, but as each set of games is intended to be one massive game in four (or three, in GU's case) parts — with each installment picking up exactly where the previous one left off, right down to details like your character's level and the items in your possession — they are closer to One Game For The Price Of Four.
Strongly averted by the newer BioWare RPGs. Mass Effect is an RPG with third-person shooter elements; Mass Effect 2 can be more accurately described as a third-person shooter with RPG elements. Likewise, Dragon Age: Origins is a relatively slow-paced tactical RPG. While Dragon Age II is definitely still an RPG, it much more closely resembles an action game due to the changes to combat system and streamlining of the inventory.
Chaos Strikes Back was originally intended to be an expansion disk for Dungeon Master, but ended up being released as a standalone game, despite being billed as "Expansion Set #1" and misleading packaging saying it requires Dungeon Master.
Dragon's Dogma Dark Arisen was never marketed as a sequel, or really anything other than what it is: an expansion pack that is sold at full price. The justification is that it includes the original Dragon's Dogma as well. That said, fans who already owned the original game were more than a little ticked to discover that they would have to go out and buy it again for no other reason than because Capcom doesn't understand how Downloadable Content works.
Golden Sun: The Lost Age is a sequel expansion pack to the first game due to not being able to fit both games onto one Game Boy Advance cartridge. The sequel reuses a lot of core mechanics such as the sound effects, NPC sprites, the battle mechanics, and list of skills.
Final Fantasy X-2 is a direct sequel to Final Fantasy X, which reuses the majority of the areas and assets that appeared in the previous game. Even returning characters Wakka and Lulu appear unchanged, even though the former had gained some weight and the latter was pregnant. Other than new areas and characters, the only change to the sequel was the battle system.
Though most all of the Touhou games are fairly similar, Shoot The Bullet and Double Spoiler are essentially the same game with different enemies. They even have the same name in Japanese.
The R-Type games for the Japanese PC Engine are a literal example of this trope. Hudson (the developers of the PCE port) were unable to port all of the arcade version's stages into one HuCard due to memory constraints, so they split the game into two halves. R-Type I contains the first half of the game, while R-Type II (not to be confused with the actual arcade sequel of the same name) has the later stages. However, when Hudson later made the American TurboGrafx-16 version, they released it on a larger HuCard capable of containing the entire game. The full game was also ported to the PC Engine Super CD as R-Type Complete, with the addition of cutscenes and a Redbook audio soundtrack.
While the first Wing CommanderExpansion Pack was exactly that on the PC, it was released as an expansion pack sequel on the Super Nintendo due Wing Commander not being worth a highly expensive pass-through cartridge (like Sonic and Knuckles).
Descent II was essentially Descent with new weapons and robots. It used the same game engine, and played much like the original.
Further, Descent Maximum for the PlayStation was Descent II with all-new, albeit half-heartedly designed, levels.
Doubling the number of weapons and items in the game and adding high resolution and CD audio is pretty big jump for one year (1995 to 1996). Also Descent II turned down the brutal Nintendo Hard difficulty of the original down to a more reasonable level.
RollerCoaster Tycoon 2, which has been nicknamed 1.5 by the critics. The third game however made major changes like switching to full 3D.
Animal Crossing is essentially the same game, released over and over again with small cosmetic changes. Animal Crossing: City Folk, is still the same game as the original Japanese one on the N64, but with some shops shifted around, about 5 new characters, and a higher resolution. In fact, it's closer to the DS game than the DS game was to the original N64 and GameCube games.
Harvest Moon: Animal Parade is this to Harvest Moon: Tree of Tranquility.
Before that, though not truly a sequel (it's more of a counterpart for Sony fans), there was Harvest Moon: Back To Nature to Harvest Moon 64. It was so well received though, that it displaced the original and is now the most common source the characters of it are based on. Back to Nature however is better than most other examples at this, considering it's essentially a completely different game with the same characters and design.
The X-Universe had this with X3: Albion Prelude being essentially built from the same engine as the previous game, X3: Terran Conflict. Albion Prelude required an install of Terran Conflict, and it added very little new content aside from a new plot, a few new ships, and some interface and AI changes. X3 Reunion was somewhat of a Mission Pack Sequel to X2 The Threat; while it had a new graphics engine, it changed relatively little in regards to gameplay.
Questionable with regard to X2 vs X3. Whilst the principles of the game (Fight, Trade, Build) don't change the actual game itself had a physics and combat overhaul, total economy overhaul, AI improvements, every ship was remodelled and redesigned and every sector was redesigned. Its a bit of a stretch to call that a Mission Pack Sequel.
The Guild 2 standalone packs Venice and Renaissance. One was panned by the community while the other is somewhat better received since the pack was worked on by former members of the now defunct company 4head games.
While all the Ace Combat games do play rather similarly, the only true case of this is Zero to 5, which is so apparent to the point that they even share a few maps for different missions. Zero does add even more planes, even more enemy aces and an Assault Record to keep track of them, as well as the return of multiple special weapons per plane and split-screen multiplayer from Ace Combat 04, however.
New Little King's Story, if taken as a sequel, is extremely similar to the original game, with many of the same events happening in the same order as they did the last time, and near-identical gameplay. It's marketed as and in many ways qualifies as a remake, but its plot portrays it as a sequel.
Most officially licensed sports games, such as the Madden series and other related franchises that release a new installment each year, with the only differences being extremely minor tweaks and roster updates. You can basically skip nine out of ten Madden games if you don't want to sort through all of the Mission Pack Sequels.
If you want to count professional wrestling games as sports games, then the long-running WWE-licensed SmackDown!/SmackDown! vs. RAW series would most certainly count. Each year brings a new iteration of the series, and while they do add a couple of new features and wrestlers into each game, they inevitably remove a couple more for reasons good or bad. Then there's the fact that the gameplay's felt the same since the very first game (which came out on the original PlayStation in 2000) even with tweaks and changes over the years, and the fact that the series has been recycling animations since the very first game (with several animations in the most recent iterations still coming from the very first game.).
The surprisingly great Disney's Extreme Skate Adventure was this for Tony Hawk's Pro Skater 4. While a lot of mechanics were toned down for younger players and the soundtrack was horribly short, it had more levels, which were more interactive and inventive than the levels in the original. Oh, and there's a Tenacious D reference.
Tony Hawks' Underground 2 Remix for PSP was this to the original PS2 game. It simply adds 4 more levels to the game - Kyoto, Santa Cruz, Atlanta, and Las Vegas. Kyoto and Santa Cruz would go on to be playable in Tony Hawk's American Wasteland for PS2, and the other two would also be available in the US only Tony Hawk's American Wasteland Collector's Edition for PS2.
A sequel to the arcade version of Punch-Out!! was produced, titled Super Punch-Out!! like the later SNES game. The only differences between the two arcade games, besides the opponents you face and haircut of your character, is the addition of an extra button used for dodging attacks (which is required to avoid certain moves) and a more detailed display of top scores.
The MSX versions of Track And Field (also known as Hyper Olympic) and Hyper Sports split the original arcade games into two and three installments, respectively, though with some extra events added. Hyper Sports can be considered to have been an Event Pack Sequel in the first place, since not much was changed from the original Track & Field except for the types of events offered.
Thief II sort of fits this trope, since it runs on the same engine as Thief and uses the same menu interface and the same mini-movies when you die or beat a mission. However, there is a lot of gameplay refinement that makes it a worthy sequel; it just technically isn't anything that couldn't have been done in the original game.
Splinter Cell sequel Pandora Tomorrow fits the description as far as the single-player campaign is concerned, which was even shorter than the original. Pandora Tomorrow was the first Splinter Cell to feature multiplayer, but that was essentially a separate game in the same box.
While Resident Evil 2 was a very different game from the first Resident Evil, Resident Evil 3: Nemesis reused the same engine as 2, but with a couple of new features such as the dodge maneuver and the ability to make your own ammo. A portion of Resident Evil 3 is even set in the same police precinct where Resident Evil 2 takes place. This pretty evident by its working title of "Resident Evil 1.9/2.1" (the actual "Resident Evil 3" ended up becoming Resident Evil: Code: Veronica).
Resident Evil Outbreak File #2 makes incremental updates to the first Outbreak's general gameplay, but otherwise is exactly the same and likely would have been Downloadable Content if said game was released for the PC, PS3, or Xbox360.
Third Person Shooter
The third Syphon Filter game, despite having you play as a variety of characters, was nothing new. Every character was just a skin, and handled exactly the same as Gabe, to the point of being the same height — even the big black guy and the small Asian girl.
The second game was also this. Like above, Logan and Xing controlled exactly the same; the only new things to the engine were a few additional weapons.
Crusader: No Remorse, a game of 15 missions and a surprisingly detailed storyline for a mid-90s shoot-em-up, was followed up with No Regret, a game of 10 missions (though they were longer and more difficult), a few new weapons (and some weapons removed), a couple of new graphical touches, a couple of new enemies, a very straightforward plot (thought admittedly featuring live-action cinemeatics with improved CGI effects), a few of Origin's trademark awesome Feelies, some background information on the setting, and not much else. A mixup in the factory led to many copies of Crusader: No Remorse being mislabelled on the CD as No Regret.
Abe's Exoddus was just a longer version of Abe's Oddysee except for some added functions on top of the original nine speech commands that made the PlayStation version nigh-unplayable. Considering that Munch's Oddyseechanged formats to 3D, that may be preferable.
In fairness, it wasn't supposed to be a true sequel. The stated goal for the Oddworld series was to have 5 "true" installments, each completely different, and for each installment to have at least one "bonus game" that kept things mostly the same. Exoddus was the only one of these "bonus" games to be made.
Ghost Recon Advanced Warfighter 2, particularly the console version, is more or less the first GRAW with a new campaign and some gameplay tweaks.
Turn Based Strategy
Advance Wars 2: Black Hole Rising was pretty much the same game as the first Advance Wars, only adding one new unit, some new CO's and a 2-tier power system. Advance Wars: Dual Strike does pretty much the same thing, adding even more new units and CO's, while including dual-screen maps and the ability to use two CO's as tag partners.
Game Boy Wars Turbo and Game Boy Wars 2 are also this to Game Boy Wars, although Game Boy Wars 2 removes one of the two cheaper indirect units. Surprisingly, Game Boy Wars 3 averts this by being based on Nectaris instead and has quite a few units even without the promoted units added into the mix.
The three Fire Emblem games for the GBA (The Sword of Seals, The Sword of Flame, and The Sacred Stones) have largely the same sprites, battle animations, items, and game mechanics; The Sacred Stones was easily the biggest shakeup of the three, but its additions were nothing particularly crucial.
The status of Napoleon: Total War is sometimes argued as such by fans of the series; some maintain that the game is a stand-alone expansion to Empire: Total War, and so should be praised for the relatively high level of improvement and innovation which it shows, while some see it as a Mission Pack Sequel that slowed down post-release development for the notoriously buggy original. The Creative Assembly themselves have avoided describing it as either a sequel or an expansion, adding to the confusion.
Turn Based Tactics
X-COM: Terror From The Deep was the same game as the original with re-drawn graphics and very minor additions, such as a few more melee weapons, two-stage missions, stat mods, and FLYING (well, swimming, really) Chryssalids.
They also made it Nintendo Hard, because no one realized that the difficulty settings in the original didn't actually work - so when some players complained that "Superhuman" was too easy, the remake crew cranked up the base difficulty without ever noticing the dial was disconnected. The bug wasn't found and fixed until years later, by modders.
Played partly straight with the sequels to Silent Storm, both of which run on the original game's engine with a few enhancements. Silent Storm: Sentinels is a stand-alone expansion pack but feels like a cut-down version of the original. The addition of the post-mission gather button feels like it could've been done in a patch. The addition of a weight-based backpack system (to the already-existing size-based one), a monetary system for equipment, and weapon degradation only serve to annoy players. Unlike the original, S3 has only one campaign (shorter too), and less options for the main character's voice (no Russian accent for a game made in Russia). On the other hand, many of the characters from the original game (both sides) are now available to be recruited. Hammer & Sickle takes place during the height of the Cold War in the same setting. The game is more RPG in style than a tactical shooter, but the essentials are the same. However, H&S does not have Game Breakers like Panzerkleins or energy weapons.
The Night Watch and Day Watch games are also based on the same engine, but the use of magic and another dimension add a whole new gameplay element. While the game includes pistols, they are almost useless and cannot be targeted at body parts.
Age of Wonders 2 was close to being this compared to the first game, retaining the same play style as Age of Wonders but with improved graphics. The next sequel, Age of Wonders: Shadow Magic was an even better example, being almost the same game, just with a new campaign and two new playable races. The recently announced Age of Wonders 3, however, is a total aversion, having very little in common with the other games in the series.
The Ace Attorney games. Okay, so the second game replaces the exclamation marks with a life meter, lets you present characters' profiles, and introduces the Magatama... but the third game adds no new features at all. Apollo Justice essentially trades all of this advancement away for the "perceive" option (the lack of the magatama makes the life meter a lot less significant). Of course, they're great games nonetheless and it would be hard to change the format significantly without ruining it.
The Ace Attorney games, actually, are the definition of Mission Pack Sequels, as, in addition to not deviating from format overly much, they also get harder, requiring more and more lateral thinking and harder logical conclusions. Try playing the first case of Ace Attorney and the first case of Trials and Tribulations and see what you think. This trope is likely the reason why fans often refer to the cases as 1-1 through 1-5 for the first game, 2-1 through 2-4 for the second, and so on, as if each game is just a part of one big game.
The general fan explanation for this is that the games are a lot like novels, so as long as the writing and plots get better, and the games become more difficult, the gameplay doesn't have to change much.
Largely due to the nature of Visual Novels this is unavoidable but still draws ire when new games contain very little to offer over the old ones. Perhaps the most notable example is Da Capo which has somewhere around 10 sequels. This is not always the case of course as often games are sold for the express purpose of being rehashes of old material called 'fandisks' and some games like SHUFFLE! Essence+ add a few new characters and some routes fans had been begging for for years tacked on to the original.
Wide Open Sandbox
The Shenmue series was originally planned to be released with serialized installments as (evident by the Japanese title of the first), but this idea fell through after the release of the first game, which is why the sequel is titled Shenmue II, instead of Shenmue Chapter 2, and spans more than just one chapter. It still reuses the same graphics and engine as the original game.
Grand Theft Auto has several games that are expansion packs towards each other. Grand Theft Auto II reuses a lot of game mechanics and sounds from the first game while tweaking the gameplay, such as being able to take a few gunshots before dying. Grand Theft Auto: Vice City is an expansion pack to Grand Theft Auto III by having new weapons and a new setting while still retaining the old stuff like specific cars (most which were changed to reflect how they could look in the 1980s) and general movement. Grand Theft Auto: San Andreas takes the expansion further by adding more vehicles, tweaking the core gameplay concept, and adding lots of new things like character stats and customization. All of this caused people to refer to these games as "the GTA III era". It wasn't until '"Grand Theft Auto IV'' that nothing but the concept of the game remained the same.
Wii Fit Plus is near-identical to the original except for new exercises and "balance games". It even allows you to import your save data from the original. Really, you might as well just trade in the original game when you get it, because it's useless if you have Plus.
Angry Birds Seasons, Rio, and Space. The concept is simple: Start each level with some birds, and use those and only those to break through a structure and kill all the pigs inside.
Intentionally invoked by the makers of Anchorman: The Legend of Ron Burgundy; there was so much extra footage, as well as a completely different sideplot involving Symbionese-esque bank robbers, that they put together a whole new movie.
Sam Flynn goes through many of the same experiences in TRON: Legacy that his father did in TRON, in the same order: getting digitized by the laser and imprisoned in the Game Grid, being forced to fight in gladiatorial combat, escaping from the light cycle arena through a hole in the wall, having an ally seriously injured (Ram dies, Quorra gets better), and boarding a solar sailer which is captured by the enemy carrier.
In spite of its acclaim, Terminator 2: Judgement Day actually fits this trope amazingly enough. Despite the dual Terminators, a lot of the film still recycles plot points, elements, and even lines from the original.
