Summary: I purchased this game mainly because of the Australian V8 Supercars series, and was pleasantly surprised by the variety on offer. So far, in about two months I've only completed a measly 16% of the game, and considering all the bonus series you apparently can unlock, that's really, really just scratching the surface.
Summary: I'll make my one and only major criticism first - the menu system. I pain to navigate quickly and logically. Playing the game however is a different experience. I didn't think this many race classes existed, let alone could be crammed into one game. There's everything from remote control cars to Formula Palmer racing. All in glarious detail. The favourite aspect is the physics and handling.
