I liked the giant horse in Zelda. I managed to ride my horses off of a cliff a few times.
I haven't picked up RDR2 yet. Rockstar's sandbox games generally aren't my cup of tea, but I like playing with the physics engines they have in them (my favorite things in GTA 4 and 5 were getting into head on collisions in fast cars and watching my character get thrown through the windshield into oncoming traffic and causing more wrecks and deaths).
I kind of wonder what was like to be the guys who had the job of designing the horse testicles. Or the guys in charge of programming the horses taking a shit.
