Currently we have a minimum requirement of 6 keep to form a map. I would suggest to have similar requirement for all the tiles example: A should contain a minimum of 6 to 9 keep / 9 to 12 mountain / 1 to 3 farms / 3 to 5 village / 9 to 12 plains -- and a map can be created using 30 to 50 tiles in total something like that -- by doing this each tile will have its own value and also brings up a challenge to better design the map with the allocated tiles. this opens up more requirement of tiles with equal distrubtion of (mountain farm keep plains ) since a person has to create a another map with the minimum requisites thus creating value for the tiles.
