All due respect, you should go back and actually look. Everything in the buildings I am speaking of, are identical - the items AND their placement. They are literally copies of one another.
Here's some examples, and these were only a handful I picked up running past. And mind you, I've only highlighted some of the objects ; the fact they are clones in every way - not withstanding.
Building 1
Building 2
Building 3 .... should I keep going?
So in short, you get all the visuals of making a mistake, but none of the penalty - unless of course you do something extreme.
I wasn't concerned about the POV, I was concerned about movement speed. You know, something very helpful when you're being chased by zombies? Again, what fear is there when you can just sprint and hop up onto a building?
I'm not making it sound like they are lazy, THEY WERE lazy. They assumed every one would be high on this gay parkour trend or happy it's basically Assassin's Creed with zombies that they wouldn't care or be bothered by a city full of redundancy. I just knew when I saw the whole city for the first time, that there would be a catch.
And in fact you are proving my point with your example. The more similar the buildings are (and in this case - identical), the easier it is to make objects/structures interactive, because the assets are already there. Now if the buildings were very unique, then the geometry would be different and THEN, it would have taken tons of time to accomplish because there weren't many similarities.
