I've been GMing a few nights a week since 1985. Started on Red Basic D&D, then Marvel TSR, Star Frontiers, Gama World, GURPS, Palladium games, World of Darkness, and on and on. Lately I have been using Fate to run many other RPG settings without tripping over antiquated rules systems. I also like running abstract settings like Bunnies and Burrows, Mouse Guard, Candyland, Wonderland, Dr. Seuss, and other weird stuff using Fate Accelerated. My favorite games are futuristic space and mecha settings, both gritty near-now, and far-future space opera.
