I love this game, but Ngl that sounds more annoying than anything else lolFor me the most significant one was no map GPS. So you have a map, but you still have to orient by landmarks, sky and logic. That made simple travel in the game an adventure. And being able to get actually lost in the woods...such a novel concept for a videogame.
Then there is less intrusive UI, no fast travel, negative perks..
As far as I am concerned hardcore is the only way to play.
