GTA III and Vice City are actually surprisingly good on mobile. I bought GTA III on a whim when I got my Nexus 7 last year with the Play store credit that came with it, and I actually loved it. It took me probably 20 minutes to get a feel for the controls and ended up playing the game all the way through after a while (halfway through Vice City now). Rockstar really nailed the controls for the touch interface, at least on a tablet.
