The Wii is stronger than the GameCube right? (Right.)

(Go about 2:00 into the video)

I think the Wii can handle several more. Maybe Dead Rising: Chop Till You Drop shows the limit, although I hope not. The NPCs obviously aren't important, but for the sake of argument......

 

I could go into a long speil but I think this will do fine:

THEY'RE DIFFERENT GAMES DOING COMPLETELY DIFFERENT THINGS.  NOT EVERY GAME IS THE SAME.
