I received this game for Christmas. My wife had downloaded and printed it at work so it was ready to play on Christmas day! Game is fun to play. The artwork, and flavor text is amusing and well designed. The game concept is similar to the PC game Dungeon Keeper, with one side playing the Pesky Humans, and the other in the role of the monsters.
After one time playing my impression is good. Some minor issues not covered in the rules, for example is movement of characters allowed through other characters both friendly and opposing. We made a house rule to cover it and moved on. The quick notes regarding game play says the final stage of a player turn is discard, yet the rules mention one sentence about discard and it is mixed with another rule entirely. We quickly came to a conclusion and moved on.
The game seems to favor the Monsters ( as implied by the game title ) Now whether that was luck of the draw, better strategy, or our house rules or some combination there of is hard to tell.
We both had fun and will be playing again soon. So I would highly recommend this game!
