This game is extremely fun. This is the first 3-D mario game, and in my opinion, it is the best mario game yet. This game introduces many new characters like Petty Piranha, piantas, FLUDD, shine sprites, and Shadow Mario. This game also unlocks some secrets in the story of Mario. It explains why Bowser Jr. helps his father Bowser capture Princess Peach.
In the magnificent Isle Delfino there is non-stop action as long as Shadow Mario and his graffiti are terrorizing the entire Isle. This game brings back old memory also. Of course Yoshi, but also Toad, Toadsworth, and Princess Peach. So it's not entirely filled with new things. This game is available at EB Games for a fair price.
