PS3 has a really nice collection of game, they are new and fresh that is a minor and a plus. Though in PS3 there is no Classic Games coming out, that's boring and PS3 has still that old control, even after sixaxis. Wii comes out whit Classic Games like Mario and Zelda. And the Nunchuk is really revolutionizer! And the wheel to Racing Games, aah, and even the normal controller, it's just fantastic! WII ALL THE WAY!
Ps3 is better for internet, graphics, and more mature based games like GTA4. But for little kids, and party games like Mario kart SSBB, and Mario Party then Wii is the way to go
This is like comparing a super computer and a blender. PS3 has upto 60 player online matches, Wii has friend code fueled 12 person online play. PS3 has state of the art graphics, wii has some higher res gamecube graphics. PS3 has an awesome collection of DLC where as Wii has just started putting out Downloadable Games wich are hardly up to snuff. Jeez I could go on all day with this crap.
