I watch a guy solve a sudoku every day. The puzzle is always different, but conceptually it's just a minor variant of the same video. I don't watch Mr Beast or that sort of content but I can't judge anyone who does.
I used to love playing Magic The Gathering. But the hygiene issues at LGS and trolling issues with MTGO left me bereft. I found a YT channel which mostly played the sorts of decks I like (control) so I latched onto that as my MTG outlet. The exact same format over and over again, but it scratched the right itch to keep me coming back. Up until they added Members Only videos.
