The most interesting bit of the interview has absolutely nothing to do with Q. Yonaga describes the creation of Route-24's Archime-DS, known here as LOL. "I don't know how many months it took them, but the staff created that game by getting together every Saturday like you would for any extracurricular activity."
LOL seems a bit less ridiculous as a side project that just ended up getting published than as a product created for a market. A multiplayer-only game with no premade content almost seems anti-commercial. But, as a "product of indie activity initiated by existing industry members," it seems very cool.
