To me, they are both winners. I loved Phantom Liberty and just started playing it again last week, only for it to be interrupted by Shadow of the Erdtree. Both DLC's reminded me how much I loved the base game and both are proper and large content additions. And they both run perfectly on Linux on day 1 <3.
Both these games and their DLC's are in my opinion what other game studios should aim for.
It is, but by god don't grind your face against bosses that are too hard. I was having a bad time when I did three major bosses in a row, now I'm fucking around and exploring it's much more enjoyable.
