I'm a pretty damn awesome player. When I play - which isn't too often. I can really get into character, since I have a background in acting and writing.
On the other hand, I am not the greatest GM, but most tell me I'm a decent one at least. I try to do voices and include in-jokes, though my preparation and description are often a bit limited.
Since I am the one attracted to novelty and reading new systems, it usually falls upon me to run the games, since I'm the only one who knows all the rules, or owns the game.
