(I posted this at Splashdamage, and it turned into a review as I wrote it.)
I love the tremors, especially in the beginning, when the bell is ringing. It brings a sense of doom and drama into the map. I also like the contrast between the ancient and modern parts of the map and how they blend in so well. The vertical aspects of the map are interesting too.
The chokepoints almost look too defensible, but I can't wait to play this map! The urn looks hard to defend, preventing the map from turning into another Gold Rush, which is good.

There is some history to this map---Mount Vesuvius did erupt during the Allied invasion of Italy.
