As previously mentioned, we now have a PS5 in the household. My handicap is that I have no experience with modern consoles, so I therefore have a few questions. Basically, we have multiple users, each with their own controller and PS account, and I haven’t entirely figured out how games, saves, and purchases work.

If offspring A buys a game, can offspring B play it? (Are the games/purchases tied to the console or the user?)
If offspring B plays a game, will his progress/savegame only be for his user?
