This bit of info was amazing.. -The higher you climb, the more severe weather you get
Maybe high winds and your stamina drains fast because of the cold...
Not sure how that can be interpeted from what you quoted. Or maybe I'm misunderstanding what you're saying and that you're just hoping for it to be like that.
Anyway, this severe weather thing was confirmed before, but in different words. It was said before that snow started to fall when you climb mountains. Technically, it's done by simply adding different weather types for the cells that are represented by mountains.
It could be cool, but it could also be bad. Why could it be bad? Sometimes you want to climb a mountain to get a great, amazing view over a valley. You know, just to be amazed by its beauty. If it gets to snow too often then, that experience will be ruined.
