So I've been trying out this mod overhaul for a few games and I have some thoughts on it.
New Resources - In my experience the new resources are spammed everywhere. Is this a known issue or am I just unlucky? Second, I came to a point where I was unable to do anything with the new resources. I remember building a quarry on a deposit of Jade once but after that I dont recall being allowed to do anything on other deposits of the new resources.
New Buildings - I feel some of the buildings should not exist. All of the Animal Market buildings should be condensed into a single building, the Livestock Market. The possible exception is the Fish Market, which should encompass all Fish and animals from the sea, like Crab and Squid.
Stable - One change that bugged the hell out of me was the change to the Stable. Why have Cows and Deer been removed from it's effect and replaced with PIGS? Cows are known as animals of burden and labor, Deer not so much, but I dont remember Pigs being used to tow things. You should restore the original effect. The point of the Stable is to create cavalry and denote that the animals are being used for labor, hence the Production bonus.
Govornment/Policies - I find that the rate at which Culture acrues severely empedes any meaningful progress in any of the govornment/policy tree's. I find that I've researched better govornments and policies by the time I can add a few points to any of them. I ended up replacing Monarchy with Republic without putting any points in Monarchy.
Oh, and this City State diplomacy overhaul might be worth adding with the author's permission.
