Forza 4 Horizons.
I have now been playing Forza 4 Horizons for about a month now, as well as getting the addons, Lego Speed Racers and Fortune Island.
Since starting I have unlocked 1500 out or 3000 points of achievements and still have plenty more to focus on. What is great about the game is the diversity of cars available as well as the different racing. To add to that the challenges are very good too, from drifting to speed zones, bonus boards to trail blazing.
If you are looking for a racing game that has plenty to offer, don't look any further than Forza 4, available for free on the Xbox Game Pass (Although you do need to pay for the additional addons.)
