Horses could also be made into amenities in Entertainment Complexes (Arena) or Encampment (Stables) gives +1 Amenity for each Pasture with Horses in the City. Or these two districts can be build on top of a Horses tile (which gives you a free Arena or Stables building instead of an extra amenity - except you have multiple horses.).

there is best concept close to history!

Please make a mod to remove horses altogether, I'd like to build over them.

@dnarik, it would actually be pretty easy to "turn off" the building temporarily. The problem is that you only need it active for 1 turn to create the trade route, then you can turn it back off again and the trade route will continue anyway. Even if I trust human players not to abuse the system, it might cause some weird AI behavior.

It would be great, if there was an ability to turn this off. For example, if you want to go to war after a period of peace and want to start building up units and need horses, but you are stuck with this building. But then, if you DO make this disable-able, then you could turn this on only once you need to make a new trade route, since old trade routes aren't stopped, if you are over your capacity

I intended it as a meaningful choice between bonus gold with GPP points and more situationally powerful trade routes. You are right about the policies, tho.

If the building was exclusive with the market, then building a Horse Caravanserai would mean losing out on things like synergy with policies and inspirations. Maybe I could add those back in as well, but what would be the benefit in making them exclusive?

tbh you should make it exclusive with market, let it have 2 trade capacities, but consume a fitting amount of horse resource. but nice work!

Hey man, just wanted to say that this mod set is really great. I love having more buildings to construct as the base amount seems to small and its even better when they use resources that I either have to many of or don't use anymore.

On a note about how the trade system works, I think you have it set fine as I imagine that the caravan takes off with the two horses which they use for the journey. The next caravan to leave would be the one affected by lack of horses, so having it set that way from a story point of view is good as for balancing I can't say.
