Some user feedback here, I just completed a 22 Civ 'Cultural - Conquest' game and let's say as soon as I reached the Renaissance it was mostly a whole world ablaze, so yeah some number tweaking would be a good idea, heck at some point I became influenced by a vassalised Brazil.
Correct me if I'm wrong but this one is actually independent of the mapsize and the number of cities from other players, it feels weird to me, instead wouldn't it be possible to have a system with both the "bonus for having fewer cities" and a new "malus for having more cities".
That one different, but I think the GW plundering is too exploitable by an human player, I always end up checking if anyone has one for trade then check for a lightly defended outpost, take it, burn it to the ground, let the war ends if there is nothing worth to take and when the peace treaty ends checking back if my favorite art dealer has something new for my collection.
I would like to make a proposition: instead of taking a GW, adding in the capital (basenumber*CityPops*EraMod*GameSpeed) points to Great Artist, Musician and Writers. It would make the conquest reward more reliable and maybe benefiting the AI in the long run.
I'm curious what the others think about any changes about the GW plundering.
