Interesting, I like that progression. Tho I think I'd suggested the geometric progression for Roan resources
Don't know how hard this would be, but here's how I think it can look a little more "natural" (besides reskinning
) -- I like the idea of a base that keeps growing. So, can the base be that geodic dome ("cottage"), then the dome expands by adding a smaller dome connected to the central dome, then the domes become more complex (e.g. add some radar or antennae or something). But the basic dome is always in the same place (the middle) and when a new part gets added it also doesn't change, it just gets gets more stuff added to it later.
Although I might back off for a second and ask what improvement this is supposed to be, since I don't recall where we left off on the improvement types. One of the ones we'd kicked around was the upgrading "habitat", an all-purpose improvement that provided some melange of all 3 yields. That might look something more like this:
1. A full dome, completely enclosed, with some grass and buildings inside.
2. The dome picks up some "wings" -- mini-domes like I suggested above.
3. The dome "retracts," and you can now see all the plants and buildings that were implied before.
4. The base structure is all that's left of the dome (a metallic ring), and the improvement covers the entire tile with some trees, grass, buildings, etc.
Maybe at 3 and 4, some kind of force field replaces the dome?
Maybe a good way to make this easier is just to cut and paste stuff from existing resources/improvements? E.g. borrow a tree from the forest, the dome from SoTM, some buildings from anywhere...
