* The CGI trailer for the first AssassinsCreed game had Altair using a crossbow to dispatch a crusader. The crossbow would not appear in the series until [[AssassinsCreedBrotherhood two games (or 309 years) later]].
** The launch trailer for AssassinsCreed2. While none of the visual content is missing from the final game, the trailer is narrated by a much older Ezio with a rather different voice. Even after two additional games of Ezio getting older and VocalEvolution, we've yet to hear him sound anything like that.

* The initial release trailer for ''BattlefieldPlay4Free'' included a scene showing combat on the Operation Road Rage map from ''{{Battlefield 2}}'', yet the current playable map roster only includes the Karkand, Sharqi, and Oman maps (again from ''[=BF2=]'').

** Continued in ''{{Disgaea 4}}'', with each segment (Save for the last one) having little to do with the next chapter, and always involving Valvatorez's sardine obsession in some form or fashion.

* Generally speaking, many developers like to take a screenshot of the game that was generated over the course of several minutes by a supercomputer and imply that it will look just as good at home with a smooth frame-rate. Such screenshots have been dubbed [[{{Portmanteau}} Bullshots]].

** "New dances" for the players we cut from Wrath, yet still played in the early advertisements.

* In an unusual twist, you shouldn't trust the ''demo'' of the PC port of ''{{Wipeout}} 2097/XL''. It supported both the newfangled Direct3D thing and regular ol' software emulation, although the latter was a lot slower. Still, given that this was the era when only high end gaming rigs had a "3D accelerator card", this was a good trade-off. The release version however lacked the software emulation mode despite being identical in every aspect other than having more content. The game [[PortingDisaster did]] not sell well compared to the PSX version, but leaving people stuck with a working demo and an expensive frisbee couldn't have helped.

** On the opposite end of the spectrum, though, the old "What a Wonderful World" commercial for Tools of Destruction gloriously [[AvertedTrope averts this trope]] for the most part [[hottip:* :(ignoring the Enforcer that got blasted within the first two seconds (while that ''does'' appear in-game (and they ''are'' present on Kerwan) you don't get to fight them before entering the Polaris galaxy) and the Alpha Cannon's presence (again, not available until later))]] the majority of the commercial showed you ''exactly'' what you'd be doing in the first level of the game: shooting stuff, getting shot at by Tachyon/Tachyon's forces, grinding on the mag-train rail (and, by extension, avoiding running into mag-trains), lobbing fusion bombs at drophyd troopers, and freefalling. Oh, and [[StuffBlowingUp blowing stuff up.]] ''[[BeyondTheImpossible Definitely]]'' [[BeyondTheImpossible blowing stuff up.]]

* The commercials for ''GrandTheftAutoIII'' included a gorgeous white Banshee (a sports car based on the Dodge Viper) with a black stripe down the middle. However, the Banshees you steal in the game only have white stripes. Cue minor bitching from fans.

* In the trailers for the video game ''{{Portal}}'' they have a scene were the player has to outrun a crushing ceiling with spikes next to a pit full of flames. This scene does not actually appear in the game. There is a third-party add in, however, that does include it as a separate game from the regular game of Portal. It's a level add-on called ''Portal: The Flash Game Map Pack for Portal'', available from http://wecreatestuff.com

* Some of the scenes in DeusExHumanRevolution, while the riot happens you never see the Tyrants actually appearing on scene to crush the rioters who begins fighting violently with the cops and PMC as [[spoiler: Two of the Tyrants are killed off long before the riots]].

* Trailers for the second episode of ''[[MonkeyIsland Tales of Monkey Island]]'', ''Siege of Spinner Cay'', explicitly show a scene with Elaine commenting on Guybrush's clearly infected hand. This is only half-true: she ''does'' comment on Guyrbush's hand, but [[spoiler:she's commenting on his complete and total '''lack''' of a hand, as he instead has a hook there - the hand gets chopped off in the first two minutes of play. Presumably Telltale deliberately lied to keep this twist as a shock]].

* [[http://www.youtube.com/watch?v=sy1eg9Dt_Iw&feature=sub This trailer]] for ''DeadSpace2'' portrays the game as an Action Shooter with mild horror elements, when we all know the [[HighOctaneNightmareFuel true nature of the game.]]

* ''TransformersWarForCybtertron'''s opening depicts [[BigGood Optimus Prime]] and [[BigBad Megatron]] facing off while two HumongousMecha (yes even compared to Transformers they are this) Trypticon and Omega Supreme prepare to fight. In the actual game, Optimus and Megtron never meet in person, nor due Trypticon and Omega Supreme, though they do still appear as the final bosses of both campaigns.

* Nintendo's ads for ''EarthBound'' pushed the ToiletHumor to BeyondTheImpossible levels with the infamous "this game stinks!" ad campaign; it memorably declared its subject to be "the first RPG [[DidNotDoTheResearch with BO]]", which it... kinda isn't. As ''anyone'' who played the game will tell you, the humor is much more intelligent and subtle, with only a few potty jokes here and there. Financial reports indicate that Nintendo put ''millions'' into this misguided campaign. It backfired spectacularly and the game became a financial disaster for Nintendo, to the point where they're [[NoExportForYou highly reluctant]] to take another chance on the franchise even though it's since become one of the most beloved CultClassic games.

* [[http://www.gametrailers.com/video/exclusive-us-record-of/60352 This trailer]] of ''RecordOfAgarestWar'' makes it like the game is a very naughty [[{{Hentai}} eroge]] on console and a turn-based strategy being its second purpose. While the game do features sim dating system and suggestive CG, the main plot of the game is a regular no-nonsense war and politic genre. There isn't even full nudity in the game like how the triller misleaded by using pixelization.
