Super Mario 64 was the first 3D Mario game. You play Mario who has to rescue Princess Toadstool from Bowser. You play the game around the Princess' castle. You enter levels by jumping into paintings hanging around the castle. Each level has six objectives. For clearing an objective you get a star. If you get enough stars you can open new doors in the castle and enter new levels. You will fight bowser three times, by grabbing him by his tail and swinging him around, and throwing him on one of the bombs on the platform on which you're fighting him. There are a lot of levels and objectives to complete so you will be playing this for quite some time.
