Yes I know. But still I feel it should be there.
I've Played Simcity Buildit (for mobile) and in that game you can unlock new terain at the edges of the map. It would be nice if EA added such a functionality to Simcity.
So you CAN build on that one plateau and you CAN access the shores that are now just a bit beyond the edge of the map or add some Highway access points, not just one that keeps clogging up.
There are some mods that do all this, but they don't work propperly.
