I am a D&D player since I was 16 and I donned the mantle of Dungeon Master at the age of 18. Until now I have garnered experience not only in D&D and its different editions but also Shadowrun, Vampire the Masquerade and even Exalted.
My favorite though remains D&D 4th edition for its fast-paced adventuring and role play enabling features, by supporting clearly defined rules and leaves little space for rule lawyering and game table arguments.
