Should have been tweaked more in the 2 years it took them to port it, but it grows on you!
There is also a Free Ride mode much like the Driver series, in this mode you'll drive around at your leisure finding things to do, people to shoot and cars to wreck, you can't carjack too many cars at first, you'll need to progress through the Story mode to "learn" how to get inside and start them up. But it's much more apparent in Free Ride that the draw distance is not up to par. Considering this game was out 2 years for PC before it was ported to consoles makes you wonder why it isn't so appealing. All in all you'll probably be able to get over the sloppy graphics, get used to the antique cars and enjoy Mafia just how it is.
