NOTE: This is a demonstration of a single trick, not really a scenario. However it is posted here as a scenario so I will grant it the dignity of a review.
Playability: 3. It's all over in 30 seconds or less, win or lose, so it sure doesn't drag on too long. I played about 10 different ways trying to get the trick.
Balance: 2.5 You are totally outnumbered but you can win by superior sneakiness. I like that.
Creativity: 3.5. New trick to me, maybe it's been used before but I haven't stumbled upon it yet.
Map: 2.5 Perfectly artificial looking, perfectly ugly, but perfectly functional which is all you need.
Story: 1.5. None needed I guess, but I bet I could have made up a humdinger. See, once upon a time there was this house, see, across the other side of the entire Black Forest that absolutely positively had to be destroyed overnight...
Comments: Highly recommended for download in case you don't know the trick already, very useful in case you get yourself into some unwinnable scenario that the designer himself couldn't even win (not that THAT would ever happen) and you need an exploit to get yourself through a tough spot. And no, I won't divulge it either, figure it out yourself. (Thinking... gee I bet you could use this to destroy a Wonder across the ocean without ever leaving home -- not that I would ever be that underhanded...)
