does anyone remember Beta tapes? how they where overrun by VHS? same thing happened to Sony again. the PS3, as of now, is just too overpriced for the average gamer. Hell, all the systems are, exept perhaps the Wii, which is why its doing so good. and this is the reasn why many games are shying away from being Sony exclusives- if not many ppl have a PS3, then where is the justification in producing a game only on Blu-Ray, but then nobody buys it b/c they cant play it?
the safest bet, i would say, is the 360. but since you father is paying for it, i belive, then you need to get the console that will satisfy you the most.
