For starters, he was the co-creator of ''Rockman''/''Franchise/MegaMan'' (alongside Akira Kitamura) but [[FranchiseZombie split]] from Creator/{{Capcom}} to [[StartMyOwn form his own company]] named Comcept.

Despite all the praise he deserves, he more or less had a long-term rivalry with Capcom's [[MoneyDearBoy money-driven]] marketing for the ''Mega Man'' series, and this resulted in complete disregard to his wants, culminating in ''VideoGame/{{Mega Man X}}6''-''X8'' and an altered plot to what Inafune had planned for the ''VideoGame/MegaManZero'' series. After more madness with the games and the production of ''VideoGame/MegaManLegends 3'', Inafune [[RageQuit left]] the company, which caused ''[[UpdatedRerelease Ultimate]] VideoGame/MarvelVsCapcom3'' to be what it is now, and presumably also caused the [[ScrewedByTheNetwork scrapping]] of ''Legends 3''.

Also makes a cameo at ''VideoGame/HyperdimensionNeptuniaMk2'', ''as a summon!''

Following his cameo in said game, people thought he was working [[ on a new project called]] ''[[WordSaladTitle Overwhelming Game Infinite Souls]]''. [[NamesTheSame They]] [[ were wrong.]] His real new game is called ''King of Pirates''.

He launched a Website/{{Kickstarter}} campaign for ''VideoGame/MightyNo9'', a SpiritualSuccessor of ''VideoGame/{{Mega Man|Classic}}'' featuring a protagonist who can use PowerCopying to [[TransformingMecha transform himself]]. The Kickstarter was successful, needless to say.

He is currently launching another Kickstarter on the development for ''VideoGame/RedAsh'', another SpiritualSuccessor, except for ''VideoGame/MegaManLegends''.

Inafune maintains a working relationship with Inti Creates, a video game company itself comprised of ex-Capcom staff, who aided in the creation of the ''VideoGame/MegaManZero'' and ''VideoGame/MegaManZX'' series, as well as ''VideoGame/MegaMan9'', ''VideoGame/MegaMan10'', and the aforementioned ''Mighty No. 9''. Their first self-published game, ''VideoGame/AzureStrikerGunvolt'', was developed with Inafune's input and had additional cross-promotion for ''Mighty No. 9'' in the form of ''Mighty Gunvolt'', a free add-on title for those who downloaded ''Azure Striker Gunvolt'' by November 28, 2014. It features [[{{Retraux}} an imitation of 8-bit graphics]] (like the ''Mega Man a'' mini-game in ''ZX Advent'') and [[EarlyBirdCameo Beck as a playable character]] alongside Gunvolt and Ekoro (of ''Gal*Gun'', another Inti Creates title).
