The Race of Champions is a real-life motor sports competition that takes place once a year for charity. Each team consists of two top drivers from a given country and the teams compete against each other in time trials to see which country comes out on top.
Unfortunately the Germans have a habit of winning, but don't let that put you off this neat digital recreation of the event. It lets you race a range of different cars, from ROC buggies to World Rally cars, around the various tight and twisty tracks that have hosted the compeition over the years. The free version only allows you to compete against your own best time, but if you pay to unlock the full version of the game (for $3 using Facebook Credits) you can play online against other players.
Neat graphics, good gameplay and an interesting array of cars make this a good little racing title.
