With this set, I now own all three D&D adventure system products,  (WOA, Castle Ravenloft, Legend of Drizzt) as well as two Dungeon Command sets. I first bought Legend of Drizzt (easiest of the three) and found it to be a superb dungeon romp. Castle Ravenloft is brutal, a meatgrinder. WOA takes the middle ground, for the most part. There are times where something leads to multiple monsters spawning at one time. If you are playing two-player or solo, this will wear you down. One scenario calls for you to take out 12 monsters. Sounds simple, right? It would be simple, except that Ashardalon's card is in that deck, too. EVERY time we play this scenario, Ashardalon's card shows up late in the game, usually when the healing surges are already used up. Still, this game is quite a bit easier than Castle Ravenloft, tougher than Legend of Drizzt.
