DRAW YOUR OWN SHARPIES RULE! Or be like me and force someone to draw for you.
I play for 5 minutes then DEMAND the person nearest me (friends, girlfriend, mom) draw a picture of what I just played on the disc. If nobody watched, I explain the game to them, then have the person draw what I just explained.
Among my vast collection of drawings are a drunk sonic, incorrect equations (geometry wars), and a dog barfing a flower (okami).
