A group of friends has decided to play through 7 Mario games over a weekend in hopes of raising some money for charity. All the money is going to Child's Play.
They're playing Mario 1, 2, 3, Mario World, Mario 64, Mario Sunshine, and Mario Galaxy. It's pretty fun to check out. I've left it on in the background for a good chunk of the night. Right now they are done with the 2D games and are 50 something stars in Mario 64.
