Im not sure why other reviewers give this game a low score, but I do not share their experience. This game is the best racing game for OS X, and I have played most of them. Its far more realistic than most racing games, both in the racing and in the scenery, which to me is a great plus. Yes, you have to practice a little and develop more skill to play this game versus some other racers, but its not really that hard -- just use the brake, and dont mash down on the accelerator all the time. My computer meets all the system requirements, which the description does mention/emphasize. I would pass on this game, and I think the developers would intend for you to pass on it, if your system does not have the right graphics card and/or system memory. Thats just a common-sense precaution. For a real console-style racing game, I have not seen a better game than this. I am very impressed and pleased.
