User Rating: 9.4 | TrackMania Nations: Electronic Sports World Cup PC
Multiplayer is a breakthrough. you never spend much than 7 minutes on track, it's fast paced, you cannot hit other players, some custom tracks are just out of this world. The controls are very easy to grab, you don't have to be a tough racing gamer to enjoy this game. The fun part is that it's actually a world-cup competition, where all cars are liveried by a chosen country, (about 100 or so...) all colors and flags noticeable on the cars, even.... the national anthem for the winner!!!!!!!! If you have a controller, a minimum 3-4 year hardware, a internet connection, and no money: this game is yours.
