I had something like this with Final Fantasy IX. Like two-thirds of the way through the game, there’s a minigame that crops up where you have to use a chocobo to walk around these tiny scenes and peck to try to echolocate hidden treasures within a time limit. And I don’t know why, but I got totally addicted to that stupid little minigame, to the point that I kind of broke my brain and had to stop playing the entire game. I did later see some dorm mates in college getting frustrated with that task and get to just zip right through it for them, though, which made it feel slightly less like a savage waste of my lifespan.
