I’m going to give an explanation, without having a single clue as to whether or not is accurate.

Encryption keys can have many layers, baking in different expiration dates. Rotating one might be required without needing to rotate all.

MH: World is the only MH game I tried, out of curiosity. It ended up on my library at some point as a PS+ game. Got through the initial “story” thing, if you can call it that. The tutorial. Getting to the camp. The mandatory chat with 10 different people. Did the first real “hunt”.

It seemed to mind bogglingly boring, that after that mission, I just uninstalled the game.

Wilds looks amazing. Which makes me wonder if the games are sufficiently different that it might be worth give it a chance.
