I played a few maps in the workshop and after looking around for something more challenging i decided to create my own map for the game with a twist.
The Rim
The object of this map is to supply the cities on the upper outer rim of the crater and the three Mega cities in the base of the crater, you could try using planes but the cargo is limited so best used for passengers (and much more fun to use trains).
What you need is a network of trains in a slowly rising tunnel up to the rim however it will take many billions to tunnel up to the outer rim and setup the infrastructure to supply these cities so you will need to plan carefully to amass the money you will need to do the job.
Link to map on steam if anyone want's to give it a play through
