Tectonics

Put it in PublicMaps and hold shift to clear the cache the first time you want to run the game if you get errors with the map file. The map provides several water/land options (from islands to pangaea), but is very random. You may get mountain ranges in the middle of a big landmass (Himalaya) or near the coasts (often hills and peaks, sometimes mostly peaks). Resources are standard.
