I know, there are already threads about disctict costs. I don't know if I am doing something wrong, but in my experience the production cost of everything except the wonders, workers and ancient units is too high. Settlers: okay, I understand that the settler cost goes up to counter city spamming. However, it seems to be to much: while going wide seems to be the optimal strategy, settling more than 6 cities seems to be the waste of time: even with the discount policy the new settler takes too much valuable time of your city production and reduces its pop by 1. With the increased district cost, building the new city after classical era almost never worth it. In my last game there was a huge empty continent. I feel like the colonial time 50% settler/tile cost reduce card should do something more to encourage rapid expansion. Districts + Buildings: Their cost increase seems to be too much. Also, I feel like the industrial district is a must-have district in every city - I personally don't think that this is right, as there should be some flexibility. May be the district itself and workshop also should extend their effect to 6 tiles without overlapping. Units: I feel that unit price is high enough to make corps and armies useless. After ancient era I barely have production to make a frontline during the war. After my capital grows to 5 pop I usually need something like 4 turns to make a warrior. In the lategame I need 11 turns to build an infantry, which is supposed to be merged into corps/armies in that era. I think that unit cost curve should be more smooth. Also, I have a feeling that AI builds the most cost-effective units available - that's why it often has hordes of warriors/chariots up until midgame. It possibly chooses the most outdated units from the production point of view. Do you have the same feelings, or am I missing something? Thank you. UPD: Those are observations for Standard Map Size, Standard Speed with 8 civs.
