A couple of minor comments and questions:
- The +1 food pr. specialist for Republic seems quite strong, even with the malus to cottage growth - it depends a bit on the civ and how dependant they are on cottages obviously, but yeah. A human player could abuse it quite a bit with the wonder that gives +1 food for priests as well, but I guess we can abuse a lot of things no matter what the setup is.
- With regards to Samarqand, would it be wildly ahistorical to have it spawn (in a 3000BC game) 1 tile west of where it spawns now? I was btw a bit confused that the Greeks have historical green tiles both north and south of it, but not Samarqand specifically, that is red to them - it's red surrounded by green. Is that a conscious decision?
- Barb galleys (called Norse in-game) spawns too early in European waters, I've seen them in 2-300 AD. There shouldn't be a lot of Viking ships rampaging at that time, as far as I'm aware.
- What is meant to be the counter for pikemen? Do they really need 100% bonus against all melee, how about just 50%? They appear OP to me.
- I may be nitpicking here (read: I probably am), but shouldn't the Isolation civic text rather say that you get one plus specialist in each core city? When first reading it I thought that it was your capital that gained a specialist pr core city, but I may just be stupid.
- What are the current rules for the expiration of the TC corp? Was there a certain tech that preventing it from spreading further to your cities after you researched it, or how is it?
- When I compare the Dutch starting situation in the 1700AD scenario with a spawn from a 600AD start, it seems nigh-on impossible to reach what is supposed to be the historical situation in 1700 in that timeframe. Even if you are lucky and the other Euros have left you the colony spots you want to build, I don't see how it's possible to get the beakers and production you need for the relevant techs, buildings, and settlers. Even if I have a perfect game and everything falls my way, and nobody attacks, you have no change of getting enough production in Amsterdam to build the TC national wonder early enough given how fast you are able to get the tech. They could use some help somehow if they are supposed to reach their historical situation.
