Been playing RPGs since 1992, DMing more often than not since 1995. Played a lot of GURPs, Mekton, Robotech, and 2nd ED back in the day, but converted over to 3.0 with everyone else in 2000. It helped that I worked for Wizards for a bit at the time. Continued on playing mostly 3.X, with excursions into World of Darkness, Exalted 2.0, and other one-shot systems. Not a huge fan of 4th as I feel the story-telling capabilities are much more limited, but my players love it and that sort of dictates what we play. That said, I try not to DM 4th too often.
