Mama Smurf said:RPG - Not a problem.
FPS - Better than ever.
RTS - Better than ever.
Fighters - Problem, easily solved by releasing an add on with face buttons (as many as the game needs, shoulder buttons if it wants it).
Platformers - Not a problem.
Racers - Not a problem/better than ever.
Action/adventure - Better than ever.
Flight games - Better than ever.
Puzzlers - Not a problem.
God games/puppy sims - Better than ever.
Music games - Probably needs an extra peripheral but always has.
Party - Not a problem.
Sports - Well...you tell me. Don't play them much. IGN seem to think they'd work.
When I say better than ever, I mean on a console, I don't know how it'll compare to a PC set up yet.
smart man, you are.
