No doubt, San Andreas, the game itself is huge, and it never ends, you can explore the map for a year and still not discover it all. Plus it had a lot of different in the missions. The music was good and the rest of the game was just amazing. Vice City was good, but I hated the shooting part because it wasn't realistic at all, all you saw was a line of smoke from the gun you fired, but I loved the music in it, and the missions was also different but not as fun as San Andreas.
