Another shout out goes to maxr: https://www.maxr.org/ It's an open source clone of M.A.X. - Mechanized Assault and Exploration. An imho excellent turn based strategy game that has aged very well. It's pretty much multiplayer only though.

Holy crap, I haven't heard that name for a long long time. I played the heck out of M.A.X. back in the day. I'll check maxr out!
