I enjoyed all of them, but I think San Andreas might be the best one ever. Vice City holds a special spot with me, but San Andreas was just one huge, great adventure. I'm currently playing it on PC, and it is still amazing after all these years.
I have memories of playing San Andreas as if I was actually in the video game. Maybe because I played it so much.
Since GTA V is never going to drop, Rockstar should re-release San Andreas for the current systems, with current system graphics.
Side note: I killed my gangsta girlfriend because that bitch ran her mouth too much. Then I was kind of sad because I couldn't date her anymore. After a while, I was hoping that she would reappear.
it's a toss-up between vice city and san andreas. they both captured the time periods perfectly(80's for vice city...90's for san andreas)and they both had amazing soundtracks. they should do a gta set in the 70's. all that great 70's music would be crazy.
