I hate football/basketball video games.... they never change. All there is, is some better graphics. In my opinion they still SUCK. Probably won't be any fun until like 10-20 years from now. When we can probably make all the movements with yourself not our hands.
I might get a PS3 just for Madden. All of them are good but I heard that that Madden 13 is a big improvement. As for NHL, it gets bored after a while IMO.
I already know I'll spend/waste too much time playing so I might hold myself back from buying :P
