One major island and three tiny islands that end up being a tweaking beachhead because it's like a very tiny arena with one airfield\town and two GV spawns into that confined area to slug it out. Everything is so close, terrain sculpting booboos and painting booboos are brutally obvious. And then there is tweaking the approach to the town from the spawns so GVers get those long views to look for snipers, hiding places to hide or snipe, and just the right amount of "no trees" to make a GVer feel like moving off the spawn because he can see into the distance. I spend a lot of time on the ground with each spawn trying to think like a GVer and tweak the landscape to be fair to both attacker\defender.
And then bridges over streams........ I am burnt out building mountain ranges and working them around those white base placeholder squares. "Place Holder" describes how much detail work I will have to do once I put the objects in place. Fortunately during one of my burn outs on mountains, I worked on GV spawns with the available village\agrarian clutter tiles so I have a semi mass production rational. The previous terrain taught me about working that out ahead of time so I had my GV centric testing worked out for spawns and sending GVs at a target.
You can see I'm almost finished creating all of the islands.
But, I realized I was avoiding grinding out another island when I started finger painting this on the island I was working on. There is a white place holder square for a small airfield with map room on the field and a stream with bridges will stand between the spawns and the airfield. I'll run a stream out of one of those runoff ravines after I drop in the small airfield object.
