To anyone interested, here is a link to a map I made for me and some friends.

This map has combines the narrow passages of Black Forest with the huge resources in the middle similarly to Gold Rush. There is a twist though. The crater in the middle is poisonous. Make sure you go there with a large number of healers. In terms of gameplay mechanics each unit in the crater takes 1 damage per second.
Have fun mates!
