I actually had no idea what a horse looked like until I played Ocarina of Time. Life changing experience.
But seriously, I hate horses in games. The only one they were good in was RDR, and even that kinda ruined it by keeping you from making a connection with your horse, even though it added realism I guess. It's more hassle than it's worth in games like Inquisition, and in games where it's needed like Shadow it's just annoying. I guess Epona isn't terrible, but she isn't useful either. Maybe in the new game.
Horses are boring animals too I think.
