I think any game where you get a horse, or other animal companion, if they want to really sell to me the bond between horse and rider they need to let me take care of my horse
what if your horse eats turtles and apples and you can raise it from an egg and if you do a good enough job it can fly or stomp really hard and it can occasionally speak to you but only in its own language and is a dinosaur / dragon thing
Have you seen windstorm: the legend of khiimori? It’s a game in the works still but from playing the alpha test I’ll tell you that you must care for your horse
