Finally someone has threaded the needle between survival game and horse girl sim [The Legend of Khiimori]

The Legend of Khiimori is an open world survival sim where you play as a horse courier in 13th century Mongolia. I've jokingly called it 'Death Stranding but horses' and, after playing six hours myself, that description really isn't too far off. Naraa the courier has to make deliveries between Mongolia's historical Yam postal stations, connect more stations to the Yam network, balance the weight distribution in her mount's saddlebags, and chart slow and thoughtful routes through the hills of the steppe.

Sounds really good, actually.

The horse riding parts were my wife's favourite part of Red Dead Redemption 2. She's going to love this.

Death Stranding with horses is what came to mind for me too so I'm very interested in this one.
