I haven't played a role-playing game since about 1980 or 1981.
I DM'ed exclusive from then till 1984..took 15 years off, and then started up as a DM again...
Honestly there are very few rpg's I really like running these days...including 3E...most are too complicated, I spend more time worrying about rules (as do most players) than telling a good story. Though, I did have fun with Exalted and WEG Star Wars, which are pretty easy to run...
But playing is an entirely different story...I'm up for anything....Rolemaster, HERO, 3E...
