You could potentially have a marketplace for this sorta bitchat puzzle/ storyline mode thing which would involve paying to play the puzzle/read the altbook (or whatever ofem or takes). As well as free to play.

Perhaps there will be another which would involve participants winning a prize or a job in the CIA lol.

You know like that circadia thing?

The geocaching Treasure thing is another perhaps obvious integration¯⁠\⁠_⁠(⁠ツ⁠)⁠_⁠/⁠¯
