You still can't hardly find this game for less than $10 even used, so a patched DRM free version for that much is more than worth it. This isn't a game that's for Flatout/Burnout fans, its more along the lines of Forza. Its very realistic, I would highly recommend a joystick/analog pad for this because the slightest mistake can send you spinning (like a real rally race).
Pros:
Good Graphics
Great effects/damage models
Detailed fun tracks
Super realistic driving engine
Cons:
Doesn't work well with a keyboard
Almost too realistic, driving in the rain and mud is almost impossible
So yeah, not much wrong with it, just remember, this game is almost realistic to a flaw. If you liked Forza or any of the CMR's before this one, you'll love. Acclaimed to be one of the best rally games ever. I loved it.
