Well, as a motor-racing nut anyway, I find it a bit addictive!
It's difficult to say about the graphics - the Mac I have isn't the latest and has a fairly stock card in it and I'm playing on a 22" monitor, so I imagine the system is a bit pushed, but I get by fine. I reckon a 17" monitor would be best for an average Mac setup.
I don't think it can be played online, but there is a multiplayer network option.
Regardless of anything you might like to put Schuey in

, unfortunately the game doesn't let you do that. But you can really cock up your race by fiddling with car's setup.
And the keyboard control is awful, get a Logitech Force-Feedback steering wheel with pedals. The game is only £30, the steering wheel for one lousy game is £120
