My first attempted map City in the woods: now also has a winter version with rare blizzards (about 30 min in between) and cold effect. Popcap is at 350 so you don't have to worry about that.
The map is centered on a rather large city on an island surrounded by a river. The rest of the landscape consists of small chunks of forest and some hills. I tried to create a symmetrical layout so that there is no advantage for either side.Also, resources are evenly distributed and there is only a slight advantage to the team controlling the City. In the winter edition there are two additional fuel points added, so controlling the city is more vital in the Winter edition (but it's harder since there are more passages over the river (ice).
