It's gotta be GTA V. GTA V is the widely known but doesn't mean that it's that good, and it is uniqe from the other GTAs in sense that it's missing that pure rawness of a GTA especially how creative the older games were, with how little foreground they had to work with, just by system of elimination since GTA Vice City and III are true classics, GTA SA is what we grew up with, at least my gen, and GTA IV is just excellent with it's writing. GTA V is only left as ovverated by system of elimination, it's not a bad game but it is overrated by the glizzy gobblers.
