There's a good selection of cars with the full roster of the WRC teams and cars combined with the 50 year anniversary mode along with a very impressive array of tracks.
However, you can't escape the fact that the controls on xbox/PlayStation controllers are absolutely atrocious. The cars are twitchy and nervous, with the slightest adjustments leading to a big accident and tiny adjustments having an unusually large impact on handling.
This game shouldn't have been released with the controller handling in this state. I read other reviews before purchasing warning people of this issue and I wish that I'd taken more notice. DO NOT BUY THIS GAME IF YOU'RE PLAYING ON A CONTROLLER. you'll have a terrible time with a lazy, half-baked game that the producers must have known was bad from the get go.
