Well GTA3 improved on the first 2 with losing the "above only view". Vice city brought helicopters, "flying" planes, and motorcycles. As well as Ray Liotta. In this one you can swim, do tricks on bikes, upgrade cars, ect... It Looks fantastic.

The Doc

And you liar, teller of tall tales: you trample all the Lord's commandments underfoot, you murder, steal, commit adultery, and afterward break into tears, beat your breast, take down your guitar and turn sin into a song. Shrewd devil, you know very well that God pardons singers no matter what they do, because he can simply die for a song.
