I am Mario. I like to jump around, and would lead a fairly serene and aimless existence if it weren't for my friends always getting into trouble. I love to help out, even when it puts me at risk. I seem to make friends with people who just can't stay out of trouble. What Video Game Character Are You?

I am a Pacman Ghost. I like to hang around with friends, chatting, dancing, all that sort of thing. We don't appreciate outsiders, and do our best to discourage others approaching us. I enjoy occasionally wandering around randomly, and often find that when I do so, I get to where I wanted to be. What Video Game Character Are You?

I am a Gauntlet Adventurer. I strive to improve my living conditions by hoarding gold, food, and sometimes keys and potions. I love adventure, fighting, and particularly winning - especially when there's a prize at stake. I occasionally get lost inside buildings and can't find the exit. I need food badly.
