Most open worlds replicate countryside areas, and as such, they are bound to be seen as "empty" by urbanites. One thing I'll give to old Asscreed games is that their cities were always fun to explore, even as walking sims.
This is something I don't get.
Why does every square inch of a game world need some bespoke content?
maybe it's because of my upbringing in which I was dragged, begrudgingly, to the great outdoors and made to appreciate nature for its own sake, but part of what I loved about Breadth of the Wild was how much of its world felt like natural wilderness- devoid of necessity for the player.
There was
plenty of cut and paste content, having a bit of negative space improved the world, not diminished it.
I'd rather have a pretty vista than be forced to fight the same Watch-Dog monster 21 times (or Hippogryff as the case may be.)
Hell, in the Chamber of Secrets game for PS2 my favorite thing to do was fly around the school and go places you wouldn't expect. There were wizard cards in some of those places, but mostly you flew to the top of Hogwats just to see the game world.
