Nintendo's Yoshiaki Koizumi is no stranger to great Nintendo franchises. Over the years, he's worked on the Zelda series and the Mario series, and somewhere in-between he helped upstart the Big N's Tokyo studio, which developed DK Jungle Beat. But going forward he'll surely be known as the man behind Super Mario Galaxy. IGN recently caught up with Koizumi to discuss the hit platformer's development process.
IGN: What do you think is the one thing about Mario Galaxy that you're most proud of?
Yoshiaki Koizumi: Oh, just being able to make Galaxy at all. (laughs). Actually, the one thing I wanted to communicate is the possibilities for co-op play, in the form of Co-Star mode. This type of co-op play is not something I've really seen before, and I think we found a particularly good implementation in the game.
