For starters, he was the co-creator of Rockman/Mega Man (alongside Akira Kitamura) but split from Capcom to form his own company named Comcept.Despite all the praise he deserves, he more or less had a long-term rivalry with Capcom's money-driven marketing for the Mega Man series, and this resulted in complete disregard to his wants, culminating in Mega Man X6-X8 and an altered plot to what Inafune had planned for the Mega Man Zero series. After more madness with the games and the production of Mega Man Legends 3, Inafune left the company, which caused Ultimate Marvel vs. Capcom 3 to be what it is now, and presumably also caused the scrapping of Legends 3.Also makes a cameo at Hyperdimension Neptunia mk2, as a summon!Following his cameo in said game, people thought he was working on a new project called Overwhelming Game Infinite Souls. They were wrong. His real new game is called King of Pirates, which ended up, sadly, being canceled.He launched a Kickstarter campaign for Mighty No. 9, a Spiritual Successor of Mega Man featuring a protagonist who can use Power Copying to transform himself. The Kickstarter was successful, needless to say.He is currently launching another Kickstarter on the development for Red Ash, another Spiritual Successor, except for Mega Man Legends.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 Mega Man Zero and Mega Man ZX series, as well as Mega Man 9, Mega Man 10, and the aforementioned Mighty No. 9. Their first self-published game, Azure Striker Gunvolt, 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 an imitation of 8-bit graphics (like the Mega Man a mini-game in ZX Advent) and Beck as a playable character alongside Gunvolt and Ekoro (of Gal*Gun, another Inti Creates title).He has recently undergone a bit of Controversey since the Mighty No. 9 kickstarter, however. Alongside cancelling King of Pirates, the Red Ash Kickstarter not only failed, but with the reveal that the game would be co developed by a chinese company anyway, many called Keiji Inafune a con-man. Not helped by Mighty No. 9's delays and marketing campaign being abysmal at best.
