Fast game
The single player in my opinion is surprisingly good because you get to choose from four different game modes which are quite fun.You can either get a Bronze, Silver or Gold in each mode.
One of the game modes is Race which is just like you're normal style racing in Track mania.
Another game mode is platform in which you've got to at least complete the track mostly you fail by falling off the track. The 3rd game mode is called stunts which is personally my favorite. The object of the stunt mode is to get as much points as possible and find the exit before time runs out. The last game mode is an old classic called puzzle in which you're in charge of building the start to finish. In the puzzle mode the levels become increasingly difficult and need some thinking to complete.
The Mutiplayer is what this game is all about. You can play against lot's of people online in which the Nations track is the most used from what I see.
You will spend hours playing this game if it's something you're into. (GREAT GAME)
