Would be kind of funny to see the different stats that would change if a family was able to pass on the full account. Like maybe one child didn't give a fuck about games (outside of just signing in here and there to keep it alive and update stuff like email and security) and no other activity. But then their kid goes hard into games and see the gaps of time. There would be lots of accounts that may have super awkward stuff like hentai visual novels. lol. But seeing some stupid high amounts of achievements and total hours of play time would be neat.
But not exactly shocking that these digital accounts would not have the ability to go much past your death. Unless we see the very deep change of all companies allowing people to remove a game and basically "gift" it. Which I can't see happening. Even physically having discs/carts hits a limit after so long. Normal wear of use and the material rotting does mean it is likely those would also not survive past a couple of generations. And that ignores the same issues afflicting the consoles needed to play the media.
So basically the real solution to both the digital and physical passing games (or music/movies) is to rip DRM-less copies and keep the needed tools to either use the game without having the disc or needing to register to a server that is likely gone. Might be a good idea to leave ReadMe instructions along with the iso/rom and copies of the official and community patches that help with new OSes. After that it is basically just down to needing virtual machines or some other PC emulators to run old emulators.
