So I found on Strange Magic a very cool series of GM Merit Badges. I'd thought I would link them here and see how all us GMs compare and contrast with each other. But don't just post the image - tell us how it relates to you!
My games will tell an interesting story - I place a huge amount of emphasis on the story of my games. If my players are not just as interested in the plot, the drama, their relationships with the rest of the NPCs, then I see myself as having failed at my job.
My games use a pre-made Map and pre scripted content - I see this as directly related to the importance of storytelling in my games. It is hard to tell a good, gripping story when you don't know what is going on. You need to pace, you have to know your NPCs inside and out. Improvising is good for laughs, but for "serious" stories you need to have an outline of the story, with plenty of room for player influence.
My games include Disturbing content - This is Warhammer. It comes with the territory! But in my Mage campaign, which deals with the corruption of power, I play this alot in terms of what Mages will do in order to create the "better world".
My games focus on interesting Characters and Drama - Another direct result of the importance of storytelling in my games. I encourage my players to think up of interesting characters, as well as flawed ones, and their inter party and outer party relations are especially emphasized.
I play By-The-Book and "rule-zero" is not being used to alter existing rules - I usually don't have major issues with the rules in my games. If I don't like the rules, I don't run it. If I like the setting, I use a different ruleset.
Character death is likely in my games. It wasn't before, but now, definitely...
Rule Zero is in effect. We can't let the little urchins have too much fun...
When players attempt to use ALL their character abilities to overcome their opponents, instead of just the smacky ones, I am well pleased.
I tend to let the dice where they may.
