It's simple, it's Mario 64 on Nintendo DS. It comes complete with a bunch of fun mini-games which really adds to the value of the game. It's a great value since Mario 64 was a great game and you don't need a 64 now to play it. Plus it's portable. The game works exactly the same as it did on the 64. It's lost nothing in this port. This was one of the first games on the DS, and a great addition.
really nice game, especially if your one of who love the updated old school games....really fun to play, although some people hate going back ................its still the same but its fun and worth passing the time :P
