Castles and Citadels and stuff

Aran is no more a rush map than it is a Water map.

If 'coming into conflict with another player before you are ready or turn 30' is the definition of 'rush' then pretty much every map that doesn't have upward of 300+ provinces is a rush map depending on the players.

I personally categorize a rush map as something under 60 Provinces. Urgaia and Sundering are what I would consider 'rush' if I were to categorize them in that fashion.

Aran, Eye, Karan, Europe, Inland are what I consider "Midsized Maps" which you can play whatever type of game you want based on the # of Players.

World, Oriana are 'long term' maps, where even if you have 17 Players there is a chance it can be rush or slow, just depends on placement.
