My favourite is the Xbox 360 because you have more choice in games. And Xbox live is much better than online gaming on the PS3 but the Wii is just for little children ..
Xbox theres most games and it has good online play only negative things is that live costs and Red circle of death or was it like that but what ever Red circle of death is that your Xbox goes poop and when you open it theres red circle at the console instead of Green that happens for like 40% of xboxes
Well, they all have their perks. Wii is fun to play, Xbox 360 (I think) is a better gaming experience and has a large gaming community, and PS3 has good graphics. If I had to pick one, I say X360.
