But why "section off" characters at all? Obviously now-a-days, sectioning off content for unlocks is meant to appeal to the casual gamer who just wants the sensation of feeling like they're "accomplishing" something. That can be saved for other things that don't affect the main game and the "chess-like" aspect of fighters that Harada and a few others have cited. Costumes, mini-games and things of that nature should be good enough, so that people who just want to jump to training mode and learn a specific character don't HAVE to grind out a few play-throughs of arcade/story mode just to unlock somebody that they want.
