I was going to say mind based magic, but then I realised I enjoy messing with heads whenever I get the chance, and I'm pretty good at that in real life. Uh, Idealism. In games, I always play an idealist first, whenever it's allowed. Real life? I'm not a jerk but I'm hardily that idealistic. Swordfighting is another thing. Can't do it myself, but in games, oh man. And a third would be swimming through waters filled with monsters. Me? I have an unnatural fear of crabs.
