Yeah, I see this as a design flaw in Civ. Better to limit the player's moves per turn to keep things moving. There's a game called "Ozymandius" that I quite like, or for a simple online game try Compact Conflict:

Hopefully the LLM's will get fast enough so we won't need to multitask, or least we can juggle fewer tasks.
