A remaster of the Wii game ''VideoGame/SonicColors'' and VideoGame/SonicFrontiers were also announced.

* ''[[VideoGame/XenobladeChronicles Xenoblade Chronicles: Definitive Edition]]'' came out just 11 days before the 10th anniversary of its original Japanese release date.

** For the 15th anniversary, Sega released ''Puyo Puyo! 15th Anniversary'', which brought back older characters that had been missing in the ''Fever'' games. Also has a multitude of modes and story routes to play.
** For the 20th anniversary, Sega released ''Puyo Puyo!! 20th Anniversary'', which invited characters that debuted or returned from ''Puyo Puyo 7''. Like 15th, there are a multitude of modes and story routes to play, and even more treats like retro spells from ''Puyo Puyo CD 2'' and ''Puyo Puyo Sun'' via cheat code.

** Nintendo and HAL decided to go even bigger with ''Kirby'''s 25th anniversary, commemorating the occasion with plenty of new anniversary merchandise, a [[https://www.kirby.jp/ new website in Japan]], themed artwork posted on the franchise's Twitter account, themed pop up cafes titled "Kirby Cafe", and an orchestrated concert. Nintendo and HAL would also release ''VideoGame/KirbyStarAllies'' later the same year, which appropriately enough, serves as a massive love letter to the franchise as a whole, a fact that is made all the clearer by the addition of Dream friends, which saw the return of many ''Kirby'' characters, [[TheBusCameBack some of which hadn't been seen in decades]]. [[spoiler:Kirby's classic ''Dream Land'' design can even be unlocked and playable as an alt skin]].

** To celebrate the 30th anniversary of the ''Mega Man'' franchise, Capcom announced the release of ''VideoGame/MegaMan11'', the first game in [[SequelGap eight years]] since the release of ''VideoGame/MegaMan10''].

* Franchise/{{Kirby}}:
** While previous anniversaries were celebrated in a low key fashion, Nintendo and HAL decided to go all out for the franchise's 20th anniversary, which they would do so by making a CompilationRerelease for the Wii titled ''Kirby's Dream Collection'', which compiled all three [[VideoGame/KirbysDreamLand Dream]] [[VideoGame/KirbysDreamLand2 Land]] [[VideoGame/KirbysDreamLand3 entries]], ''VideoGame/KirbysAdventure'', ''VideoGame/KirbySuperStar'' and ''VideoGame/Kirby64TheCrystalShards'' in one package. The compilation also contains additional content as well, such as an art book and soundtrack that come with the game, an in-game museum that goes through both Kirby's history and real world events that coincided with the games, on top of containing a couple of episodes from Anime/KirbyRightBackAtYa, and new challenge stages based off of the ones from ''VideoGame/KirbysReturnToDreamland''.

** Unlike the last two anniversaries, which were given a ton of focus by Nintendo, the 35th Anniversary of the series in 2021 was not celebrated with much fanfare by them, with Nintendo outright admitting to have no major plans for the anniversary during E3 2021 (disappointing many in the process). That said, they still celebrated it in a more low key fashion. In addition to an UpdatedRerelease of ''VideoGame/TheLegendOfZeldaSkywardSword'' in July, a UsefulNotes/GameAndWatch-style handheld was created in a similar vein to the one made for Mario's anniversary with the original ''VideoGame/TheLegendOfZeldaI'', ''VideoGame/ZeldaIITheAdventureOfLink'', ''VideoGame/TheLegendOfZeldaLinksAwakening'', and a variant of the classic [=G&W=] game "Vermin".

** The 35th Anniversary of the series in 2021 was similarly subdued, yet not wanting for content. In addition to an UpdatedRerelease of ''VideoGame/TheLegendOfZeldaSkywardSword'' in July, a UsefulNotes/GameAndWatch-style handheld was created in a similar vein to the one made for Mario's anniversary with the original ''VideoGame/TheLegendOfZeldaI'', ''VideoGame/ZeldaIITheAdventureOfLink'', ''VideoGame/TheLegendOfZeldaLinksAwakening'', and a variant of the classic [=G&W=] game "Vermin".

* Similar to the way they celebrated [[Franchise/SuperMarioBros Mario's]] 25th anniversary, Nintendo created a similar package for Franchise/{{Kirby}}'s 20th anniversary, complete with book and soundtrack. However, since Nintendo didn't previously make a Kirby anthology, this release is all-new, including a museum mode giving details about the series.

** The 30th anniversary will be the aptly named ''VideoGame/SuperRobotWars30'', which will have the honor of actually being the first game is the series with licensed characters to be released in North America and Europe.

** The 25th anniversary will be ''Original Generation'' sequel ''The Moon Dwellers'', which will have the honor of being released ''in English'' for non-Japanese regions.

** Sonic's 30th Anniversary saw the release of the ''Sonic the Hedgehog Encyclo-speed-ia'', a comprehensive encyclopedia on the lore and history of the main series titles written by long-time ''Sonic'' comic writer Creator/IanFlynn in his first job at handling material for the games. A remaster of the Wii game ''VideoGame/SonicColors'' and an untitled 2022 game were also announced.

** Followed by a smaller update exactly a year later which adds another special world seed accessed by typing "celebrationmk10" or numbers corresponding to the update release date or Terraria's original release date ("05162011", "05162021", etc.). Doing so spawns you on a painted beach on either side of the world with a party immediately started and several NPCs, three of them named after the lead developers.

** Capcom celebrated Mega Man's 25th anniversary with ''VideoGame/RockmanXOver''. However, after the negative backlash the game received, they supported the fan-made (and much better received) ''VideoGame/StreetFighterXMegaMan'' as an anniversary game for both franchises.
** To celebrate the 30th anniversary of the ''[=MegaMan=]'' franchise, Capcom announced the release of ''VideoGame/MegaMan11'', the first game in [[SequelGap eight years]] since the release of ''VideoGame/MegaMan10''].

** ''VideoGame/PacManWorld'' was released for the 20th anniversary -- [[LampshadeHanging the plot is even based on a villain crashing Pac-Man's birthday party]]. ''Pac-Man World 3'' would later be released for his 25th anniversary.
