Legend
I play to make the world my own. That doesn't mean conquer it(but it can). It means that the world is my play thing to support MY goals and MY focus of play. The notes are secondary to that.
So let's separate character and player.
What do you do as a player that makes the fiction ("world") your plaything? How much of that fiction is up to you to establish? Are you limited by what your character can do and accomplish? How are these things resolved?
There probably isn't only one answer. But I would say the more that the answer involves the GM deciding how things go, the more play is in fact shaped by his "notes".
Which sounds to me like what's expected in your play, based on your other comments.
It's not discovery. It's creation.
It can be both, absolutely. I have discovered lots of things through play. I just last night learned that a PC of mine is a bit of a coward in some ways. Wasn't really what I had in mind for him at the start of the campaign, but it's what I happened during play, and it absolutely was a discovery.
The way he described it was the players sitting around discussing what sorts of things to "discover." By the time they settle on something, any surprise and discovery is over with. They know the options and voted for the one they prefer most.
So then the only way players can discover is if it's something that the GM has decided, and then they somehow learn of it in play? Is this what you mean?
