** '''Capsule Pitch Description:''' Fantasy isometric [=RPGs=] based on the UsefulNotes/D20System.

** '''Capsule Pitch Description:''' Hybrid Rhythm/Action games where the player plays a monochromatic shape that has to avoid other monochromatic shapes that move to the beat.
** '''Implementation:'''

** '''Capsule Pitch Description:''' Multiplayer ActionAdventure games on the UsefulNotes/PlayStationPortable

** '''Capsule Pitch Description:''' Both are ActionAdventure games developed in Japan by Creator/TeamIco and Creator/PlatinumGames exclusively for Sony's UsefulNotes/PlayStation4 and Microsoft's UsefulNotes/XboxOne respectively. Both games have a human protagonist accompanied by a pet (a griffin and a dragon respectively).
** '''Implementation:''' ''The Last Guardian'' was announced in 2009, originally for the UsefulNotes/PlayStation3, before getting stuck in [[{{Vaporware}} development hell]]. ''Scalebound'' was announced in 2014, but there was no information about it for a year afterwards. The main difference between them is that ''Scalebound'' is much more action oriented than ''The Last Guardian''.

** '''Implementation:''' ''Breath of the Wild'' was the latest entry in the long running ''Franchise/TheLegendOfZelda'' series, being both a launch title on the UsefulNotes/NintendoSwitch and the final first-party game on the UsefulNotes/WiiU. ''Horizon'' is an original IP on the UsefulNotes/PlayStation4, the most popular console of the generation.

** '''Implementation:''' Both games were very graphically impressive for their time and played a big part making the CD-ROM format take off. Neither game had much, if any, character interaction or text and instead focused on visuals, atmosphere and abstract puzzles. Interestingly, both were originally released on the UsefulNotes/{{Macintosh}}, a format known for its lack of original games.

** '''Capsule Pitch Description:''' Trilogies of urban {{Beat Em Up}}s released on rival platforms (''SOR'' came out on the UsefulNotes/SegaGenesis, while the UsefulNotes/SuperNES got ''Rushing Beat''; ''Final Fight'' came out before either in arcades, but its first console port and two sequels were on the SNES).

** '''Implementation:''' ''Star Raiders was'' Creator/{{Atari}}'s KillerApp for the Atari 8-bit computer line, with ports to the Platform/Atari2600 and Platform/Atari5200. ''[=StarMaster=]'' was made by Creator/{{Activision}} for the 2600 as an unlicensed third-party title, while ''Space Spartans'' was a space combat sim by [[Creator/{{Mattel}} Mattel Electronics]], originally released for the company's UsefulNotes/{{Intellivision}} console and later for the much more popular 2600 through Mattel's M-Network division.

** '''Implementation:''' ''Ace Combat'' was released early in the UsefulNotes/PlayStation's life to rave reviews and had several sequels. ''Airforce Delta'' was released for the UsefulNotes/SegaDreamcast launch. The first ''Sidewinder'' was released one year after the first console ''Ace Combat'' and attempted to distinguish itself with somewhat more realistic elements.

** '''Capsule Pitch Description:''' Modern combat flight sim franchises. ''Ace Combat'' was formerly console-only[[note]]''VideoGame/AceCombatAssaultHorizon'' got a PC release via UsefulNotes/{{Steam}} in 2013[[/note]] while ''HAWX'' has both console and PC versions.

** '''Capsule Pitch Description:''' Arcade-style flight combat games released in 1995 for the UsefulNotes/PlayStation.

** '''Implementation''': ''PSO'' was originally a UsefulNotes/SegaDreamcast exclusive, while ''FFXI'' saw both a PC release and console release, being a flagship title for the UsefulNotes/Playstation2's Network Adapter add-on. Both games have also enjoyed [[LongRunners great longevity]]: ''FFXI'' has remained in active service and received new content since its original 2002 release, happily coexisting with its successor, ''VideoGame/FinalFantasyXIV''. ''PSO'', meanwhile, found new life on the UsefulNotes/NintendoGamecube, UsefulNotes/{{Xbox}}, and PC after the Dreamcast was discontinue. Even after the official servers for the last version of the game, ''Phantasy Star Online: Blue Burst'', ended, the game lives on in countless active private servers that run nearly every version of the game to have been released.

** '''Implementation:''' ''Second Life'' (and many of its competitors) is all about user-generated content; everything in the game (outside the tutorial items) was made by ordinary players. ''Home'', on the other hand, is more structured, with all content made by the developers, keeping it rather family-friendly (and advertiser-friendly) by comparison. In addition, ''Home'' is only on UsefulNotes/PlayStation3, while ''Second Life'' and most of its other competitors are for computers.

** '''Implementation:''' At the time that ''[=PSO2=]'' launched, the original iteration of FFXIV was four months from being shut down, having been an abysmal failure. Eventually, FFXIV relaunched as ''A Realm Reborn'' and proved to be much more successful than its predecessor. ''[=PSO2=]'' was originally slated for an international release shortly after its Japanese launch, but the development of the international version languished for several years until it was finally released in 2022 as a timed PC and UsefulNotes/XboxOne exclusive.

** '''Implementation:''' Though neither was originally developed by a major video game company, and both had appeared on numerous computers previously, Nintendo and Sega acquired the rights to release console versions of these games, and they were among the launch titles for the UsefulNotes/GameBoy and UsefulNotes/GameGear, respectively. (Sega also produced several ''Tetris'' UsefulNotes/{{Arcade Game}}s.)

** '''Implementation:''' ''Meteos'' was a launch title or close to it for the UsefulNotes/NintendoDS, while ''Lumines'' was the same for the UsefulNotes/PlayStationPortable.

** '''Capsule Pitch Description:''' More Victorian-era puzzling with snappily dressed protagonists, this time on the UsefulNotes/Nintendo3DS.

** '''Capsule Pitch Description:''' The UsefulNotes/PlayStation4 gets a console-exclusive Tetris game. Not to be outdone, three months later, the UsefulNotes/NintendoSwitch gets one too.

** '''Capsule Pitch Description:''' 3D overhead shooters exclusive to the original UsefulNotes/PlayStation, exhibited side by side at E3 1997.

** '''Capsule Pitch Description:''' Two snowboarding games come out for the UsefulNotes/{{Nintendo 64}} almost simultaneously.

** '''Implementation:''' Let's face it, the real fight's between the control systems: ''Wii Sports'' demonstrated the UsefulNotes/{{Wii}} Remote, ''Kinect Sports'' is made for the UsefulNotes/Xbox360's controller-less camera system, and ''Sports Champions'' utilizes the [[UsefulNotes/PlayStation3 PlayStation Move]].

** '''Implementation:''' ''Tony Hawk'' relied mostly on name recognition (with the Hawkman and several other pro skaters making appearances), while the ''skate'' series promised a different approach to trick control (utilizing both analog sticks on the [[UsefulNotes/PlayStation3 PS3]] and UsefulNotes/Xbox360 controllers instead of the face buttons and D-Pad).

** '''Capsule Pitch Description:''' UsefulNotes/NintendoGameCube-exclusive[[note]]The ''Resident Evil'' remake would later get an UpdatedRerelease in 2015 for PC, UsefulNotes/PlayStation3 and [[UsefulNotes/PlayStation4 4]], and UsefulNotes/Xbox360 and [[UsefulNotes/XboxOne One]][[/note]] survival horror games released in spring 2002, set in a vacant mansion filled with grotesque monsters and idiosyncratic puzzles. At the time, they were the only M-rated [=GameCube=] games on the market.

** '''Implementation:''' ''[=DayZ=]'' began life as a PC-exclusive GameMod for ''VideoGame/{{ARMA}} II'' that takes place in that game's [[{{Ruritania}} Eastern European setting]], eventually being expanded into a stand-alone game in 2013. ''State of Decay'' and ''Infestation'' are set in [[FlyoverCountry rural America]], with ''Decay'' available on both UsefulNotes/XboxLiveArcade and PC, whereas ''Infestation'' is a PC exclusive. Finally, ''[=ZombiU=]'' takes place in UsefulNotes/{{London}} and is exclusive to the UsefulNotes/WiiU, making use of that console's touch screen controller.

** '''Implementation:''' ''Tear Ring Saga'' is essentially a SpiritualSuccessor to ''Fire Emblem'' on the UsefulNotes/PlayStation. It was developed by ''Fire Emblem'' creator Shouzou Kaga, and incorporates the vast majority of its game mechanics, to the extent that Nintendo attempted to sue for copyright infringement. In fact, it was originally meant to be called ''Emblem Saga'', but the lawsuit prevented this.

** '''Implementation:''' Both games were designed by Creator/YasumiMatsuno and were released in the same year (1997 in Japan and 1998 in North America; release order remained the same). It should be noted that ''Tactics Ogre'' is originally a 1995 UsefulNotes/SuperFamicom game and that ''Final Fantasy Tactics'' is its SpiritualSuccessor.

** '''Capsule Pitch Description:''' UsefulNotes/Xbox360 games, [[NoExportForYou in Japan]], which had DatingSim and RhythmGame elements.

** '''Capsule Pitch Description:''' UsefulNotes/{{Wii}}-based cheerleading games.

** '''Implementation:''' ''Star Raiders was'' Creator/{{Atari}}'s KillerApp for the Atari 8-bit computer line, with ports to the UsefulNotes/Atari2600 and UsefulNotes/Atari5200. ''[=StarMaster=]'' was made by Creator/{{Activision}} for the 2600 as an unlicensed third-party title, while ''Space Spartans'' was a space combat sim by [[Creator/{{Mattel}} Mattel Electronics]], originally released for the company's UsefulNotes/{{Intellivision}} console and later for the much more popular 2600 through Mattel's M-Network division.

** '''Implementation:''' ''Auto Chess'' started off as a very popular GameMod in ''VideoGame/Dota2''. Valve attempted to contact the mod's creators, Drodo Games, to collaborate with them in making a stand-alone version of the mod (similar to ''Dota 2'''s own history as a custom game in ''VideoGame/WarcraftIIIReignOfChaos''), but found that they had already started work on such a project, so they made ''Dota Underlords'' in response. ''Dota Underlords'' thus started out as a nearly identical port of ''Auto Chess'', though later patches have since caused it to become significantly different by introducing new items, heroes, alliances, and [[HeroUnit Underlord units]]. ''Teamfight Tactics'' is Riot's own answer to the autobattler phenomenon, featuring ''League of Legends'' characters and items. Unlike its competitors, ''TFT'' is played on a hexagon-based grid, and it is played within the ''League of Legends'' client, rather than as its own stand-alone game; this also means it does not have a mobile version, unlike the other games mentioned here. ''Battlegrounds'', Blizzard's take, uses a simplified format with two rows on the field instead of a grid and combat using a fully turn-based attack order. It is also directly built into ''Hearthstone's'' client, and is available on both PC and mobile.

** '''Implementation:''' ''Crypt Killer'' had straight ''Film/IndianaJones'' theme, while ''[=CarnEvil=]'' had BloodyHilarious BlackComedy-horror in a carnival setting with killer clowns.

* ''[[VideoGame/PoliceQuest Police Quest: Open Season]]'' (1993) / ''Blue Force'' (1993)

** '''Implementation:''' ''World of Tanks'' was the first on the scene, with more focus on competitive gameplay, while ''War Thunder'' was more of a FollowTheLeader but initially focused more on aircraft. With the latest updates however, tanks are also becoming a big focus. When compared to each other, World of Tanks has a more arcade-like feel while ''War Thunder'' focuses heavily on realism, though both games have lots of ShownTheirWork between them. Over time, the games began diverging from each other with ''War Thunder'' adding late Cold War/Modern era while ''World of Tanks'' stuck to its WW2-era roots.

** ''Implementation''': ''Starfield'' was first announced in 2018, while ''Baldur's Gate III'' was announced in 2020. ''Baldur's Gate III'' spent a few years in early access, with Larian Studios planning to release the game in full in September, but moved the release date of the PC version of the game up a few weeks to get a lead start on ''Starfield'', which would release around the same time as the Playstation 5 version of ''Baldur's Gate III''.

** '''Implementation:''' At the time that ''[=PSO2=]'' launched, the original iteration of FFXIV was four months from being shut down, having been an abysmal failure. Eventually, FFXIV relaunched as ''A Realm Reborn'' and proved to be much more successful than its predecessor.
