Wii>PS3>360
Wii may have fever good games. But at least when you buy a game for Wii, you are certain that it would not freeze/have a sh*tload of glitches/DLC content which is already on the CD but you gotta DL the unlock code, and that the game was made purely for entertainment.
As for why PS3 is better than 360 imo. I think it's because that 360 was brought by EVERY 10 year old in the world at this time *excluding actual adults* and PS3 community seems a bit more mature *community that i see in games i mean*
Oh and the biggest part was probably because PS1 the first console that i saw after NES.
P.S. Did i mention that Wii STILL has gamecube compatibility?
