The concept is great, the little I have used it, wonderful!
However, it seems to have a conflict with BlouBlou's unlimited barb exp mod, as in, it doesn't work. My units exp stops where it normally would. I did the usual reloading and deleting cache stuff, but didn't help.
As I said, I haven't used this much, for the above reason. What I did notice, and this was a hotseat game, so this goes for both of us, is as follows. I have used it a couple of times with just me playing as well. But always using the hotseat mod.
Generals, they just seem to heal. I noticed no difference in exp and culture bonuses, by era, General in an encampment or not. (which is fine by me) Just taking an encampment gave me as much as taking one with a General in it, just harder because of the Generals healing and maybe defense bonus, not easy to tell on that last part.
There are a lot of Generals, not a once in a while thing, more like, rare if they aren't there.
I'll be happy, maybe, to give a list of mods I use. (if I can copy the damn list to notepad, lol) But really looking forward to an unbroke Unlimited Exp and the Capture + mod I have just subscribed to on Steam. I am not using Capture + at the moment because I wasn't sure what had broken Unlimited Exp.
I am not sure of game balance and the reward of this mod. Didn't play enough. On the surface it seems a bit high, but don't hold me to that yet. It might be fine and I would so much like to fill out my culture ladder better.
Your concept is spot on. I was so tired of killing encampments and getting a touch of gold and nothing else. Fine for starting out, but just wrong in the later game.
