Probably the best of the three D&D board games (Ravenloft, Ashardalon, Drizzt).  The game itself is a big box of stuff (miniatures, maps tile, game pieces, rulebooks), so its a lot of fun to open.  The quality of everything is VERY good, so this game is going to last a long time.  Very replayable, and even supports playing solitaire (for those nights when everyone is out of town).
