i can't decide. Labor force for slavery adn more orders would be great, but we don't really need them ATM. roads, though, are good for connections.
Polis for asking greece to DoW on someone (babs), but also walls for def and discontentment and hamlets for $$. Free UU! And the Spymaster! long, but could be worth it if we can put someone v good in that spot.
this was also my thought. extra money is nice, esp if we have a gov or leader who can buy improvements. also the -1 discontent per turn for family-defended walls; i learned the value of that the hard way in my last game. but it seems to be 2-1.5 in favor of the UU (if you haven't played yet anyway)Those are tough choices. I would have gone polis for the walls, considering Greece and Babylon, and hamlet.
