Same in terms of quelling anxiety, but I think the commenter was referencing the fact that, in contrast to the original post mentioning 'cozy' games, this commenter is talking about a highly 'un-cozy' game.

Opposite the "cozy" part of the game. OP's game is infamously challenging.

That's just marketing. It actually has one of the most fair difficulties of all "challenging" video games.

Fairness and difficulty are orthogonal to each other, no one said the game is unfair. But it is definitely very challenging, and that’s not marketing as far as I know - I have yet to see a trailer etc for the game that says anything about difficulty. Dark Souls did that a lot more with their "prepare to die edition" or the opening of DS2.

You think of Elden Ring as cozy?

Why yes, a walk in the park I daresay
