The closest thing I've got is various D&D computer games, which don't quite have that engaging feel. I don't want to sit back and watch my character chopping up monsters (a la Icewind Dale or Neverwinter Nights), I want to be mashing buttons and jumping all around the terrain (a la Tomb Raider).
I suppose I could carve foes up with my lightsaber in Jedi Knight ... but that's aliens and deckplates rather than swords and sorcery.
Woe, to be a picky gamer!
PS: What I really want is for somebody to run this. Although I'd happily play a D&D barbarian too.
