There are times when I think that the person I'm talking to, about a game we both play, is actually doing something completely different. I like to find people who can balance their enthusiasm for gaming with not taking it too seriously. I quickly tire of conversations about people's pet characters, character types, systems, peeves and campaign settings (unless the latter are home-brewed and carefully thought out). On the other forelimb, I thoroughly enjoy well-told gaming anecdotes. People who have them and can tell them in an entertaining way are people I want to game with.
That brings me to my influences. I love story telling and I like games to be the stories of the characters played. I have no desire to impose a super-sized, grandiose story-arc on a campaign though. I like to see those things emerge from the actions of players, occasionally nudged along here and there by me in the direction that seems the most promising. The other influence is wargaming. I like to play out the tactical situations that arise from combat and exploration. However, as it often gets said on these boards that wargamers have a DM vs Player mentality, I'd like to stress that I do not. I DM, as in referee; I am neutral.
I love fiction but not fantasy fiction. I picked up some good pointers from the reading list at the back of the first DMG but otherwise I avoid it. I suspect that puts me in a minority.
