You'd have to be one obsessed gaming hermit to get to the end of this game. There are 20 tracks, and 70 variations, and more than 1000 cars to put in your virtual garage.
You'll need gargantuan amounts of stamina to win every race, complete all challenges and collect all the cars available.
Perhaps a more sensible goal would be to collect the 200 premium cars that are modeled in more detail, and allow you to drive with an in-cabin perspective.
The 'Course Maker' feature is a little disappointing. Rather than letting you faithfully recreate your favourite run over the Yorkshire Dales, you're offered just a few stock options before the course is automatically generated for you.
