This is a simulator in the truest sense. As I've mentioned innumerable times, this game is detailed and realistic. It does allow you to create races that are suited to your ability. Simply put, the better you get, the harder you make the racing.
If you want the most detailed, most accurate simulation of NASCAR racing and even multiplayer up to 43 drivers, NASCAR 4 is the only obvious choice and the game deserves to be a best seller, but only if they patch the AI!
An enthusiastic and ambitious project that is worthy of any oval lover's attention. Minor blemishes aside, it is easily the finest stock car sim available and quite possibly the best racing game to date.
