I started with a homebrew system of my own, vaguely based on the battle mechanics of Pokemon in a one-dimensional battlefield. Some time later, I was introduced to D&D 4th, and from there I've explored a few other systems, including Pathfinder and GURPS. I've been running a 4th Ed. game/epic since 2011 in my own world that has grown and developed over the years, with a few smaller games and stories along the way.
