My only experience with docker is headless in CI. I do have AMD. I'll have to look into this. Thanks

Hopefully yes, because so far none of us are AI programmers...

but seriously yes everything about the game will be designed for customization

Well, "capabilities" is carrying a lot of weight there. One of the main objectives is to design it for unrestricted modding to accommodate all of the wishlisted features, but "out of the box" the default game mode will be 1:1 in mechanics with some QoL improvements. The inspiration is mostly for designing systems in a way that can be easily reconfigured or extended to behave in other ways. We hope that by the time we reach feature parity, people will have already built some mods to do things that were impossible with Civ3.

As mentioned above this was started by Civ3 modders, and we all have our passionate reasons for preferring it over other entries, but you're not wrong that doing this with a 3D engine would be a whole `nother ballgame. There are actually Civ4 and Civ5 remakes underway which have both opted for 2D implementations.

The founding developers were all software engineers with .NET experience, so it was the natural choice even though at the time it was Godot 3.x with Mono. I had used Unity before but not Godot. The project is structured as mostly plain C# DLLs with a relatively thin Godot UI layer controlling it, so the Godot type system is fairly encapsulated. We haven't really seen any issues with those decisions beyond just working out the communication between Godot and DLL. But again we were just working from what we knew so I can't really say if this was the best way to go about it.

I was also there at Civfanatics watching from the sidelines. Fond memories indeed, and some of those same people laid the foundations for this project.
