GTA Vice City and San Andreas are all you need in a computer with XP. In addition Unreal Tournament, KOTOR, Battlefield 2 are the great games which I used to love playing on my previous PC. I've stuck with an XP recently, we came to Montenegro 2 weeks ago to visit my uncle and find a property for sale in Montenegro. He has this very old computer, you can only play GTA Vice City on it. Anyway it's always fun to play this game.
