I have played, but prefer, being DM. My D&D experience dates back to 1st edition AD&D. My campaign world is based on the Farland setting with a massive amount of modification. I also enjoy using David Hargrave's world of Arduin and Warhammer 40k as additional creative devices. My game also uses a mana point system for casters in lieu of spell slots. It's easier to learn and use for both player and DM.
