I've been playing and running RPG for... 15? years. I started with D&D 3.5 in high school and continued (briefly) into 4th edition where I began to get bored of the D&D archetype. I began to branch out into other systems. WoD, Exalted, Cyberpunk, WH40k, Burning Wheel and then some. From there things get weird; I founded and ran an RPG club in College and started getting into odd Indie systems and quick and simple systems like Dread, FATE, InSpectres, Danger Patrol, among others, to run one shots for orphaned players who's group didn't show or arrived too late to join anything else.
Nowadays I'm helping plan and run a campaign for Five Rings Online, an online L5R community and playing when/whatever I can get.
