If I already have a 360 and a blu-ray player is there any reason to get a PS3?
There doesn't seem to be any must have games I can't get for the 360.
What games are there that are worth shelling out on the console for?
Well as I said in the other thread, "must have" is in the eye of the beholder, what was a great game for me, can be a "meh" game for others. (Resistance 1 & 2 are the examples I cite).
That being said, Infamous was the one game that made me happy to be a PS3 owner and I don't think I've heard much of anything but positive comments about it. But is it alone worth buying a PS3 for? Probably not, but when you couple with some of these other games like Ratchet & Clank, you begin to realize there really are some pretty good games out there.
