I have an idea that I've been kicking around lately. Its a map of the Autobahn system in Germany. Obviously not all of the routes would be used, mainly sticking with the primary single-digit routes. The territories would be cities along the various routes with some serving as junctions.
My biggest hangup right now is with gameplay. I'm not sure on what the best option would be as far as bonuses are concerned as well as winning conditions. I have a really rough draft of the map I can show right now, but was curious if anyone would like to help me with developing the gameplay.
