I'm Getting a PS3... Name 5 Must Have Games

[Gearbox]

So we all seem to agree the best would be MGS4, ratchet, GTA4, uncharted and cod? ok so 2 multiplatform games but still! If some1 asks this about 360 all u could say is halo, bioshock, cod, gta4 and assassins creed. (ps. bioshock is going multiplatform)
