In the fourth volume of the ongoing series of interviews between Nintendo's Iwata and the Mario Galaxy team, design legend Shigeru Miyamoto puts forth the opinion that he thinks he's nailed two-player Mario. That opinion is bolstered by Japanese sales figures, which shows the plumber doing quite well for his umpteenth outing. "Miyamoto: 'For every game I worked on, there were always times when I would keep discussing the issue of two-player simultaneous gameplay, and the staff also became conscious of the challenge, so every development team kept trying hard to solve it too. Though I think that might also have been because they thought if they didn't deal with it first, I'd come in and ask how it was coming along for sure! (laughs).'" Via Kotaku.
