Are there any noteworthy Civ1 and Civ2 remakes (other than FreeCiv)? I know about https://github.com/SWY1985/CivOne, which was supposed to recreated Civ1 in C#, but they stopped development before implementing the AI, which is always tricky to faithfully replicate without some solid/time-consuming disassembly of civ.exe.

Those are two games that AFAIK haven't been re-released through the normal Steam/GoG channels. Seems like only Civ3+ are available, not sure why.
