This was my suggestion of how tribal markerplace should work. I posted it last year. It seems the new african mechanics are very similar to to the ones I described: building on top of mines that generates an extra resource (influenxe instead of xp) and a building that attracts animals. Im guessing that now that the mechanics are in the game, it should be able to at least be modded in, although preferably they should be implemented in the base game.
Also, why african nations have small scale agriculture and lakota and hauds have states and farms?
