GTA: Vice City was the last one I played. I've seen videos of GTA4, but I wonder if there will there be any similar co-op/multiplayer improvements in GTA 5
GTA IV was far from "minimal specs" my GTX 480 and i7 960 @ 3.8GHz struggles sometimes, it's very poorly coded as a PC port, so if anything i hope they do a better job on the PC version of the game
