Every single country has their own "this animal is super special and has amazing history for the country". A domestic horse from central asia does not warrant more inclusion than any other animal with unique history.
However you could request a mod from one of the modders, as we already have a wild horse in the game and this is the kind of animal that would be perfect for mods.
Although I must say from pictures that horse looks amazing.
Not to sound rude, but I'd like to know where people get the idea that I'm demanding in the suggestions forum. It's a suggestion forum for a reason where players could put their ideas/suggestion for the developers to consider, not modders. If it was in my interest to request a mod to include said animal, I'd have already put in a request. I'm not threatening developers that if they didn't include the horse that I'd blow them up or something. It's literally a suggestion.
While I understand your point, you seem to completely miss mine and I'd love to clarify it. It's a suggestion for developers for their future plans. Not a demand, not a threat, but a suggestion for a possible new DLC seeing as how they already released a couple of regional DLCs.
Yet again, I'd like to apologize if I came out rude or disrespectful and hope you have a nice day!
