Windstorm: The Legend of Khiimori where you play a postal rider in the Mongol Empire seems like an Exilian kind of game? https://store.steampowered.com/app/2697000/Windstorm_The_Legend_of_Khiimori/ (warning: very computation-intensive page! I won't link to the YouTube video trailer because this forum software would embed it and that is not very privacy-friendly)
Ooh, yes, that does look very interesting! I will have to wishlist it, I'm always interested to see more non European medieval games, there aren't nearly enough such things. May have to see if I can contact the devs too...
Also, the software doesn't actually automatically embed YouTube links: it still treats them as links unless you use the BBCode YouTube tag to mark them for embedding.
