I Own This Game and it's Amazing! It takes about 3 days to finish it by just speed running each level, but if you want to clear the game 100%, you will have to take your time and use your skills wisely. Kids that work with others in multiplayer mode use teamwork.There is lots of content in this game, like challenge mode, boost rush mode and many others! It is Also easy to play! Overall it a Great Game! Every Mario Fan Should own this title!
