Myself I have never been a fan of D&D, particularly I can't stand running a D&D game, character progress so far that it gets in the way of meaningful storytelling. I much prefer the next generation of games such as Paranoia or Call of Cthulhu because you really can kill players off. Either that or games that are very simple to run like Toon. In D&D I think the game dynamics get in the way of the improvisational acting aspect that Gygax encouraged.
