Ironman, GTAIV has been released for Xbox 360 too, like GTA:SA has for the Xbox a few years ago. Not a legit arguement.
PS3 is better because if you play online a lot, then you save money because the online play is free, and the Xbox Live costs what? $50 a month? that's $600 a year, that beats the price of the PS3. so yeah, PS3 is expensive, but it's not as bad if you compare it to how much the XboxLive will cost you in the long run.
I'd rather save money in the long run than reduce the activities that I can do by $50 month
If Chess had better graphics, would more people play it?
