Just like how you're introduced to the world is literally how BoTW introduces you to it's own world (could it be a homage?), or something as simple as picking up consumables with a simple press of a button with no animations, little things that aren't in the way of you experiencing the world.
What I haven't put my finger on was how both of these games propel you to discover the world, and to find out what's above the hill or if there might be a cave in a cliff. I don't know if it's the terrain design that's actually thought through and not left to some algorithm, or if it's simply the perk of having a great brand behind these games that have rewarded us properly for exploring their previous worlds.
