GTA 3 was literally the revolutionary 3D gaming experience of the new millennium for me so I have to give it the credit here. It also felt to most like the original non-rockstar developed games. That said, Vice City was a great sequel. San Andreas was really great for the beginning of the game when you were in the hood but I felt the middle portion was really drawn out and while the world was so much larger than the previous games, the graphics actually were worse than Vice City. To accommodate the huge maps, the draw distance and jaggies were really noticeable to me back then.
