I read this post (IDEA: alternative to Tribal Market for Lakota/Haudenosaunee) and agreed with the points given there. Basically, I am on board with giving them a new way to gather coin, as I enjoy diverse mechanics, but I think the way it’s implemented now is not the way to go: it doesn’t have anything to do with fur trading (although it is mentioned in the history tab) and you end up depleting the mine anyway, which is the whole point of changing things.
So I propose the tribal market gets split in two buildings, each focusing on one of it’s abilities; generating coin and generating xp.
The first building would be the same tribal market we know but it wouldn’t be placed in mines. Instead, it would act like a shrine, atracting a max of 10 animals each (can be fewer). But the animals wouldn’t generate coin by themselves, you’d have to put villagers working in the building so it can start producing coin (only coin). It can be infinite or it can change each food point for 2 gold and dissapear when all animals are consumed. You could only build 3 at a time at can only be worked by 10 villagers at a time. The cost would be the same.
The second “building” would effectively be a sacred site you build on top of mines and generates xp by itself, like indian cows in their special building (don’t remember the name right now but it relates because religion). Another effect of this sacred site placed on top of the mines would be that they become unminable: no one can exploit the mine until the site is destroyed (or the player can destroy it to allow and ally to mine it). It relates to reality and it could make a good mechanic.
This would shift the meta of both civs to include or focus on negating resources to the enemy (hunt with the tribal market and coin with sacred sites) and map control, and you could add cards to make tribal markets trickle food or buffing sacred sites in some way.
Would you like to see the mechanic changed to something like this?
