Liberty City Stories (5-/-0/2008)
So I've spent a few hours playing GTAIV now - running around Liberty City, stealing cars, going on dates and getting cursed at by tai-chi practitioners (no, really).
It's a lot of fun, and I can't wait to try the online game, once Rockstar get around to fixing the showstopper bug that prevents the game from loading if I'm connected to the internets.
