This year at GenCon, my best friend and I are promoting 13th Age, our new fantasy RPG for people who want more story and more open-ended rules. Twelve years ago at GenCon 2000, some new friends and I were promoting D&D 3E, my corporation’s fantasy RPG. At GenCon twelve years before that, in 1988, my best friend I were promoting Ars Magica, our new fantasy RPG for people who wanted more story and more open-ended rules. I’m not exactly in a rut, but maybe I’m going around in circles.
