Super Mario 64 is a very fun and open-world game to play! It was released in 1996 for the Nintendo 64. It is the first Super Mario game to feature 3D gameplay, combining traditional Super Mario gameplay, visual style, and characters in a large open world.
In the game, Bowser, the primary antagonist of the Super Mario franchise, invades Princess Peach's castle and hides the castle's sources of protection, the Power Stars, in many different worlds inside magical paintings. As Mario, the player collects Power Stars to unlock enough of Princess Peach's castle to get to Bowser and rescue Princess Peach.
