Gran Turismo 5
The Gran Turismo series is generally considered the best driving sim game on the market. This 5th iteration features more than 1000 cars and 60 tracks for your driving and modifying pleasure.
This is also the first game in the series to feature realistic car damage – so ramming your opponents to get ahead may not be the best option this time around. Online play is available through the Playstation Network, so you can show off your ride to your buddies.
If you like racing games, Gran Turismo 5 is as realistic as it gets.
