The 360 version looks a little unpolished, and its clear the game doesn't have GTA's budget, but hey, it's looking like a nice alternative.

30 main missions, though? Hm...There was just over 20 for each GTA episode, and they clocked in at a solid 8-12 hours, even if you did the extra activities. I don't mind if the plot isn't overstretched, but I expected a bit more in that department. Maybe I'm just used to sandbox games being too long and empty, though.
