Difficulty in videogames - mainly various "assist modes", easy modes in challenging games, optional helping tools, etc.
There was a huge uproar around rumors of Dark Souls 3 getting an "easy mode", with hardcore fans making a mess over how it's "not close to the spirit of the franchise" and how it'll ruin the game, etc. But thing is, not only most of the time said features are entirely optional, but they also act as a bridge towards less involved and capable players - if anything, I'm all in for more people getting into wonderful lore of Dark Souls or enjoying the music and visuals of Cuphead, and for me, "They'll skip on some fun of challenge" definitely beats "They will never play the game because it's too hard". It just feels to me that challenge gatekeepers care less about spreading the games they love and admire, and more about their sense of superiority for beating said games, and that's kinda sad.
