Testing all the time as you build helps in surprising ways. Since Waffle put only a sand stone tile in the Med tile set, sand stone weathers in very predictable ways. So combining that with testing 660ft for that last mesa elevation, I got a good effect to use up a few miles along a river cut. I spend more time worrying about how what I create will effect tanks and that player's enjoyment than I do anything else on a terrain, go figure.
That is because they will have their noses up close and personal with the features I create around every field.
What really gives me a headache is I can see the completed terrain down to all the micro terrain features for tank combat but, creating it is like having to build a 1 mile pasture wall 5ft high with only field stones I dig from another pasture by myself. It drives me to drink, and I think my local coffee bean supplier should cut me a break for how much I buy.
You will notice I had to run a bead down the ridge line to account for how much I raised the ridge at those cinder cones.
