I don't mind cities being idle when they have built their useful parts. I'm not going to start building units in a conclave just to keep the queue full.
ofc no but there is ALWAYS something to build
even some research building to have a better research later
right now i just dont see much working
i mean i always choose to build something because if i have 50% research more for few turns then i will have 70 80 less for the next
i dont know the idea behind is interesting but it doesnt seems to work totally, but im open to hear some different feedback
