Ok, I've got an idea that I think will work. It's Civ as a clicker game. I've been playing the "Tapestry" board game lately and I've always wanted to make a "fast civ" game.

I've started on the rendering and am in way over my head with SDF hexagons.

I think I am going to back off the SDF for the main hexes though and use them for floating background stuff. I've got it pretty well thought through but there's a lot of things that could blow up.
