As a player, I definitely enjoy combat in Descent more than I do in D&D. The various action options--Advance, Battle, Run, Ready (with its subcomponents, Dodge, Aim, Guard, and Rest)--really have much more tactical depth than D&D's "move if you need to, then make an attack as a standard action" approach.While i enjoyed Descent well enough, it sort of felt slow. For what it's worth, i think that 4e D&D handles the combat and rpg aspects better. But Descent has the best room tiles and little plastic monsters, so it's still worth picking up.
