When it comes to maps, very few capture the feel they are trying to emulate. It's a hard thing to do, but it's worth talking about when its done right. I believe Simplicity attained that to it's own maximum, but fell short when it came to atmosphere. See, while it was cleverly laid out and very stylistic, it failed to build a deep sort of connection to its own setting, because while it was Simple, it was also very Plain. Let me explain. Simple doesn't always mean to the most basic of colors, designs, and ideas. Sometimes, it means to emulate an easier or less intricate way of doing things. Simplicity excels at the latter, but falls short of the former. I believe it is a great map to play once or twice, but it loses replay-ability with every map. I hope this helps.
