Surely the best kind of easter egg is one that gives the whole game away ahead of time, but which you'd never notice on your first time through. Baldur's Gate 3 does it with its music, BioShock did it with its revive system, and, hey, I guess Alan Wake 2 did it as well. Spoilers ahead for, you guessed it, Alan Wake 2.
Still here? Great. An enterprising Alan Wake 2 fan has realised that the game lets the cat out of the bag very early on with regards to Alan's evil doppelganger Scratch. If you need a reminder, Scratch's whole deal is that he's a product of the evil Dark Presence who impersonates our Alan. Or, more accurately, he possesses him: It turns out over the course of AW2 that Scratch pretty much lives inside his head.
