This driver is a good game. I've never played Driver 3, only 1, 2, and this one. The driving on this game is very good, and fun. The police on this game is more realistic, in the way they act and they way your crimes are handled, than GTA. However the shooting on this game isn't good, and is pretty unnecessary.
One problem I noticed with the game is how if you're driving a car, you'll sometimes only see that car on the street, which was a problem in Driver 2, however it happens rarely. It's a good game, but not as good as The Godfather. Buy The Godfather.
