I have not played your game, but as an avid gamer that loved hidden knickknacks (like FF7), the ability to randomly reward exploration through adding these things is beyond amazing. I hope you continue to add things where it pays to play (in rich experiences) as opposed to pay to play (those experiences) experiences.

Reminds me of Ready Player One. ;)

I think having hidden eggs, that expire after so many accounts /visitors there are would be tremendous. Even if the reward room is always the same, having some common puzzle idea mixed with the lore would be astounding. I think Guild Wars does this closest (for big game titles) but you can usually brute force their puzzles.

A long time ago, I used to create Skyrim/Morrowind content like this. Not overly complicated, but simply paying attention to details or surroundings in the game that are otherwise just world-filling-content.
