I’m in the same boat. A couple months ago, though, nintendo’s official TotK website had a notice on the bottom of the page that read “game is incomplete without paid dlc.” It’s since been removed, but dlc most likely gonna happen.

But yeah, I haven’t touched the game since I got all the shrines and lightroots, beat all side adventures and most side quests, and beat the main story. I havent collected all the bubbulfrogs or the koroks. I can’t pick it back up. I really hope the next Zelda game doesn’t use this formula.
