It's coming out in a few days, and Gamespy already has a review of Ratbags' Dirt Track Racing 2..
"My biggest criterion for judging a racing game is how well the computer-controlled cars mimic the abilities of real people. DTR2 scores big points here. The drivers behave and react like you would expect them to, making aggressive moves when the opportunity presents itself, even making mistakes from time to time."
Some other good comments in there about the game, so get on over to Gamespy and read the review.
