Well, appliances and electronics are generally getting more energy efficient.
In most places, electricity is generated and sent straight into the power grid for consumption; no batteries. The power draw is monitored and generators get turned on or off depending on the demand.
I’ve written a whole spiel in response to your comment before I realized you were talking about the difficulty curve, aka new player experience, not the difficulty of the game as a whole.
And yeah, that tracks; the new player experience in both those games you’ve mentioned (along with many other Souls-like games) is kinda bad. Sometimes, some hand-holding at the start is nice.
