This is how i rate them Games Online Special feature
Playstation 3 features Big games(200Gigs) Free online play(average package) Home
Xbox360 features Average games(50 gigs) Monthly payment (Pro package) Achievements
Wii Low games(10 gigs) Free Online play(basic package) Best way to get fit
Personally i dont care about online that much,so i vote for Ps3,hope this helps figuring out witch games you want!
PS Xbox 360 might fail in 2 years(rumour)Because the games are too low compared to their opponent(PS3) So this is just a rumour,supposed to be a new xbox in 1-2 years(Xbox 720)
