Rdr2 has really ruined horse riding in other games for me
In terms of mounts, playing ghost of tsushima and assassin's creed games after rdr2 is a miserable experience. The mounts just materialize out of nowhere whenever and wherever you call them (which is also the case of rdr1) and it breaks my immersion every time. Rdr2 having the horse not disappearing in the world when you dismount and forcing the player to be in range to call for them is one of the most genius decisions for mounts, not to mention the bonding mechanics to make players emotionally invest in the mounts.
I feel like all other open world games just treat horses as a mere means of transportation so you can move quickly from arena to arena on the map, and it's not supposed to be fun. Rdr2 horse riding is extremely fun to me. The horses feel so heavy in the way they stomp the ground. Is there any open world game that has similar horse riding experience to rdr2?
Edit: now that I'm thinking about it, the materializing mounts at the whim of your calls are very typical of 2D MMORPGs. Maybe that's a remnant of most open world games trying to adopt what worked before.
