For example, most people don’t want to die to the same boss over and over again. That’s just not good gameplay and it’s overall a waste of time.
This is a very subjective opinion stated as a objective fact. I think Sekiro, for example, is great gameplay, even when lady butterfly kicked my ass for hours.
Some people would like the difficulty automatically changing. I would hate it. I do want to lose to the same boss over and over until I get it right sometimes. That’s part of what makes clearing sekiro such a triumph.
The other from soft games are similar, but they have leveling and coop as difficulty adjustments.
But I do recognize that not everyone likes this. Even I don’t like it in every game, probably.
