It’s been known for a while now that Masahiro Sakurai, the director of the Super Smash Bros. series of video games has been having some health problems as of late, with bad problems with his arm getting in the way of the development of the new Super Smash Bros. game that’s in development for the Nintendo 3DS and Wii U. Unfortunately, these problems aren’t going away…but are actually getting worse. It was previously thought that he had repetitive strain injury, but in a recent interview with Famitsu Magazine, Sakurai has revealed that he has calcific tendonitis in his right arm as well as several ruptures in the muscles, to which there is no immediate cure. This means that using a keyboard or a game controller puts him a large amount of pain.
Sakurai also commented in the interview that he spends most of his days overseeing other people, holding other meetings and other things. Personally, I think it would be better for Sakurai and the game development team if he stepped away from game testing and code entering and simply started delegating his duties more until his health improves (or take time off work completely and letting Namco Bandai take the reigns for a while). After all, if he continues like this, his arm will only get worse.
