D&D Player and Dungeon Master, editions 3.5 and 4 with the occasional elements of 2 and 3 thrown in. I also do homebrews. I've got some limited experience in other tabletop games, but I have books for both "Numenera" and Warhammer's "Rouge Trader".
I've been writing fiction since I could read it, and I'm also a freelance artist currently going to school for animation with the hopes of becoming a storyboard and concept artist. Both of these skills come in handy when helping my players develop their characters, or creating them myself. My strongest skill as a player is my theater background. My strongest skill as a Dungeon Master is my world building. My favorite character to play is a Dragonborn Bard, but I tend to tailor a character to the story and group I'm playing with.
