Sorry, I hate this crap.
I'd rather every game have one default difficulty and maybe a harder one for NG+.
Some games are hard. Some are easy. It's all fine. The game difficulty should be part of the overall package and design of the game.
Someone gets the ending of Sekiro, they earned it. No participation award.
Someone beats Celeste, they either conquered a challenging game, or more likely, at the first sign of resistance, they turned on cheats and water-down the experience.
Not every game needs to be for everyone. But, when you're confident in your vision, including challenge level, you might be surprised that the audience is bigger than anticipated. Look at Elden Ring.
