unless it wants to play nothing but phone games on a TV
Yeah its a big point many developers today still dont understand it. The GOOD games on a platform are the one that are specifically designed for that platform; it especially makes a difference when input schemes are different.
games that were made for a controller and being ported to a touch device, just for the heck of it, will fail: see Mega Man X ios port
and of course it goes the other way too, every touch game without touch will be duller. Especially considering there is no mouse - on pc you can do a touch game with just the mouse, like cut the rope HTML5 version. a controller doesnt have anything...
my point is, for good reason there are hardly ANY android games being developed with a controller in mind
hence all ouya games will be ports... OR someone will actually put all their eggs in one basket and make it almost an exclusive for the ouya (with maybe a pc port)
android games are touch controlled, there are hardly (if any) gamepad games
porting games to a different control scheme sucks
Thats why the ouya will either have shitty ports or exclusives, which can only succeed if the console succeeds, which it wont
