Assassin's Creed Black Flag has a system somewhat similar to this. You just get a clue, which can lead to a picture on a map. Which ends up being a buried chest. It would generally lead to plans to upgrade your ship. It was a good system.
It's actually quite the shock that it is in an Assassin's Creed title of all open world games.
It's a system that is in some modern games if you look. Admittidly, this is the only one that comes to mind right now. I agree though, it needs to be more common.
