I got this "free" game yesterday and I have to say it's pretty nifty. Of course, if you're willing to part with a lot of USD you can crank through upgrades of cars and things, but it is perfectly playable without any of that. The makers of the game licensed from some major brands (Audi, ford, chevy, bmw, nissan), so the cars you race and upgrade are real cars. Given that each race--a drag race--is simply pressing of one or two spots on the screen I suspect this would work well on the iphone, too.
I imagine I'll get bored with this, but so far after two hours I'm not.
