New Super Mario Bros. Wii is an action/adventure game developed by Nintendo. Up to four players can play this game. There are power-ups in the game like propellers, ice shooters, penguin suits, fire shooters and more, they will help you to prepare when taking on things like toads and mushrooms. The game has eight worlds of exciting gameplay and when you complete all eight worlds you will unlock a special ninth world. I would rate this game 10 out of 10 and would recommend it to any family.
