We started out intending to only do the main story of Super Mario Odyssey, which we finished this past Monday. People kept encouraging us to get 500 moons to unlock the last of the super secret worlds, and we were like… maybe. But yesterday we hit 250 moons (thanks to the help of the not-very-helpful official guidebook) to unlock the first secret world and oh man. Burnout was happening quickly. So we called it quits for good after completing the first secret world in English and Japanese.
A couple years ago, we ran Yokai Watch into the ground by attempting to complete every side quest in the game after beating the main story. That burned us out on the game pretty badly and we didn’t want the same thing to happen with Odyssey.
But hey, if any of you are still working your way up to 500 moons in the game, please get screenshots of the text in the final secret world for us! We’ll pay ya for your trouble. Thanks~~
