Subnautica has a somewhat related concept which is that at the end of the game you have the ability to send a single time capsule to the maps of new players. They contain text, a picture (taken with the in game camera), and a handful of items.
It's a cute little feature that allows you to send something helpful (or just amusing) to the next generation of players.
