There was something great about the 2d versions that was in the move to 3D. The driving side of things for a start became less about the joy of tearing through a city, less of a game, and more of a way to get places. Not sure if that makes sense, but that's the way I found it. The original was a bit like Micro Machines, but in a massive city with cops and lots of guns. And you could play it over a lan - much time was lost playing GTA over my uni's network.
Old school.
Errm, it was a third person shooter?
San Andreas was my favourite.
GTA2 = awesome
GTA3 = crap.
Vice City = crap
Liberty City Stories = Enjoyable, but can be crap at times.
That's a good example of an unacceptable opinion.
