I got a copy Thursday around 1:00pm. The line was down to about 20 people and it moved fairly quickly.
We've played it three times since then as it does take about 4 hours for a 4 level dungeon game with 6 players.
It's a blast to play, the loot cards are great and each player has an equal chance of winning based upon their own strategies. It's a very strategic game in that the other players chose which monsters you will fight, the other players also decide when and if they will assist you in a fight.
The point of the game being to flee the dungeon with the most loot points for your character before the dungeon collapses (after killing Xykon of course).
I played with my wife who understands very little of D&D and she still has had a blast each time and delights in making me fight the blue dragon every time.......
Rich did a great job with it nd the room descriptions are just as hilarious as the loot. "Rooms" like the Great Gazebo (don't anger it or it will hunt you down), Janitorial closet, Monster lounge (where the monsters relax and startled to see you walk in on them having their coffee and tea) ect...
We've had a great time with it and a different person has won it each time we've played, I definately recommend it.
