I'm reminded of Bright's https://en.wikipedia.org/wiki/Empire_(1977_video_game), a turn-based PvP strategy game. My friend's 1989-ish instance was sadistic enough to batch execute four turns per day. Every player had to rush to a TTY every six hours to give new marching orders. If you study or sleep too late, your forces and factories could be wiped out.

The obsessives, living on campus newly free of supervision, were line printing maps and writing logistic planning tools that foreshadowed EVE Online's "spreadsheets in space."

I still play it. Also, XConq it's a modern rendition of Empire, written in TCL/Tk.
