Pac-Man and Mario is a shame created when Namco and Nintendo joined forces to create the ultimatest shame ever! Unfortunately, it was a great failure, like everything they try to do, and the project was abandoned. But SEGA came in, violated every copyright law in existence, and finished the shame.
In this shame, the playable characters are Pac-Man and Mario, obviously. To play, the player must navigate through the Mushroom Kingdom maze, while avoiding the Pac-Land Ghosts and Koopas. Then, the player must face Bowser and the Mega Ghost AT THE SAME TIME.
This shame was given a "We don't care." by Biased Ratings.
