Actually, I'd play that. Namco recently announced that they were forming an Apple Games division to head up game development for Apple platforms like the iPhone, and in this interview, a producer for them who used to work for Apple says that they're excited to work on bringing great games to the handheld device. Like, for example, Pac-man, Galaga, and... Soulcaliber and Tekken. You heard that right -- fighting games haven't exactly made a splash on the iPhone, as they're primarily a button-based genre, and the iPhone, of course, has no buttons.
But that won't stop Namco's guy from putting the old head gears into motion: "It's just the controls that are a challenge. We are thinking about that." Think away, crazy man -- I'd love to pull out Yoshimitsu for a few rounds while waiting at a bus stop. Obviously, the easiest way to try and port these would be to put overlaid buttons on the screen, but that doesn't leave a lot of room for the fighting (and not having the tactile feedback would probably be a problem as well). Maybe some gesture-based accelerometer movement? Sky's the limit, right?. Your call, Namco -- can't wait to see what you come up with.
