Vice City is the only good GTA game. And that's mostly because the 80's motif makes it that way.

And Crazy Taxi is the shits.

Vice City is the only GTA I cared enough for to complete. GTA3 got too annoying after a while, with all the gangs who hold vendettas against you shooting at you every time you drive by even if there's no logical way for them to know who you are inside your vehicle from a mile away. San Andreas is maybe too big and I didn't get far in it. It might have something to do with the fact that it was, for the most part, just like the previous GTAs and I was bored with the concept after having completed Vice City.

Also, as you said, the 80's motif made Vice City. San Andreas is set in the early 90's and has a more gangsta feel; I prefer the Miami Vice feel, or even GTA3's Martin Scorcese feel.
