Difficulty is much harder to research. It’s relatively easy to find if there’s depictions of drug use in a movie.

It’s much harder to tell how hard or easy a game is. I’m reasonably experienced with games, and every time I start one I still waffle over difficulty.

Dark souls often has both its difficulty and the importance of its difficulty to the experience overblown. You can still have encounters like Asylum Demon and Sen’s Fortress alongside difficulty settings.
