Well generally barracks cost 200 wood 100 stone for most civs... but the tribal ones now cost 300 wood only, 20% faster build time but 20% less health and capture points.... similar to temples, forges, all of those things are wood only.

Agreed, i these should be stone building category with different durability as opposed to wooden buildings which are pretty much the rest for most civs.

So I like this, Sparta already has the -10% pop penalty... so it should apply to Thebes and Athens?  Then Sparta may be strongest out of 3... Im tornn on citizens gather/military... on one hand sparta wasnt very eco driven right? on the other we use some melee bonus for some of the tribes as well... So we will definitely have to clean things up.  All the city states have hoplite tradition  

Yeah, I made most of their buildings cost wood, similar to the tech that already existed for "celts" but I towers, forts, and ccs are exempt

Proposal for city-states:  - citizen soldiers have better gathering and combat stats (not sure which ones to improve), but are more expensive. City-states had limited manpower compared to larger polities, but they had higher civic spirit. - population cap is reduced by 10%. Similar thinking as above.  - additional civic centers cost 50% higher. City-states did not expand like empires. All proposed city-states already have the theater to expand original area. Note: all of this is a nightmare to balance but worth a try in a mod
