From the mysterious origins of the Codex Umbra, to what brand of hair gel Wilson uses, Don't Starve lore is something of a luxury.
To my dismay, I know of a few players in real life and people I happen to play with in DST that don't know the lore of the game. To some of them, it's a game where you die a lot... most of them get bored after dying and losing their progress (DS)... I myself spend time working on my survival and taming the wilds, but on nights when we gather around the camp fire and tell stories to pass the night, most have not even heard of Charlie, save for that video in the main menu where she just appears and brakes Wilson out of the Nightmare Throne... the very threat to their survival, known only as (and I paraphrase) "That woman who was there to free Wilson, yeah, where do we see her in-game?"
All the theories, all the mystery, all the drama, the lore... and some players are just joining servers in Winter, or at night and running off into the darkness, away from the protective spot light Charlie provides you to spare you from her wrath, running around digging up mushrooms... Most people are lazy and have no time to look up the lore... they find the game interesting, but without knowing the story behind all of it, they lose interest...
And so, I am proposing that in both DS and DST, old (solved) puzzles would be present in the same way that DST has the intro-video of what happened after DS... A New Reign (goodness knows I'd like to see the Don't Starve Trailer in the DS main menu)... something like putting the William Carter Puzzles in Don't Starve... the manner in how they will be put in the game should be discussed. I for one suggest playing Adventure Mode and after conquering a chapter, reveal a link in the main menu to a/the puzzle... the more chapters finished, the more links... (forum thread or the actual puzzle)
Also, with what we have now, I still haven't found a good "Don't Starve Lore Explained" video because most channels aren't too keen on spending a lot of time uncovering the game's secrets and lore...the closest one would be:
This might evolve/devolve into a discussion about unlocking achievements, which we all know that Klei does not believe should be in Don't Starve as it pulls away from the blind and exciting survival aspect (achievements give hints... or not... discuss but keep in mind this is about lore).
