I thought of an idea to make a map that has a single "pinnacle" at the top-middle, with the bulk of the resources close to it, so the goal of the map (and the playthrough) would be to take and keep the Pinnacle! The Pinnacle being only 6 tiles, and each layer out from it being terraced shorter, eventually down to sea-level. 

The lower areas would still need some resources, so those cultures can make militaries and such (to fight their way to the Top!), but I thought it would add incentive to have most of the good ones in the territories around the Pinnacle!

Anyone know if something like this exists or would someone want to have a crack at making it?
