Fought a random group last night and one of the archers ran away, I picked up all the supplies on the ground and called my horse..... found the archer fighting a bear very unsuccessfully a bit down the road / trail.
I love that type of emergent stuff.
I wish there was more of that... I like that you can set the grass on fire too, that is very BOTW.
When you light the fire in the lighthouses, nintendo would make you do that through a mechanic rather than it happening in a cutscene....so I hope they think about making these part of the mechanics in future.
Also as we have been discussing, gambling, drinking, fishing and other activities to flesh out the world. Gwent was a big part of the Witcher.
