Is Dark Souls too difficult.
No. The answer is no. But it is difficult, and difficulty is part of its appeal to the point where people won't shut up about it.
But this video does a great job of unpacking that difficulty and explains why it's such an inextricable part of how Dark Souls works.
I think the interesting part of this video is that it's not necessarily by an 'lore expert' or a YouTuber dedicated to the series. It's by someone who enjoys video games and is literate enough to discuss the differences between Dark Souls and other action games.
I don't usually last long on YouTube videos of this ilk, but this was good. Very good in fact.
