Few kart racers stand up to the fun and pace of ModNation Racers (MNR), Mario Kart included. From the fact paced kart racing along an increasingly difficult set of opponents and track styles, the small but interesting weapons, to the seemingly endless set of props and parts for creating characters, karts, and tracks. MNR does a good job of training players to use the tools properly and showing good examples of who they're used via the single player "career mode". In it players are exposed to various track building concepts and pushed to switch racing tactics to adjust for new props and traps. By the time the game is 'over' players can either go back and earn creation items they missed or start creating and sharing.
