I think everyone doing all the side quests and shyt.
They are MUCH better than Tsushima's too.
Climbing to the top of Yotei was so dope
Yeah, they really are. Sometimes they even tie into things unexpectedly that you don't plan on doing, but end up doing as it's the task to do your actual objective at the time. Such as Altar or Shrine hunting for skill points. Sometimes those be technically "locked" behind a sidquest that you don't even know about until you get there. And along the way, you can see just random things going on that aren't even really sidequest, more like just mini-quests/random events that you can either witness or take part in.
It just flows really smooth and interwoven pretty seamlessly. And all while looking too beautiful and seeming too interesting to just bypass more often that not. So far, they're very varied

as well.
