I thknk playthroughs can make a lot of sense for some games, but it realy depends on the game. Like if it’s the Last of Us where the primary appeal is the story and there’s little in the way of plot-relevant decisions made by the player, you don’t lose much at all by not being the player. That makes sense

OP is asking why people aren’t watching playthroughs of stuff like Majora’s Mask where half the point of the whole thing is solving puzzles, though. I’m pretty sure they’d have asked me about the decision-heavy RPG I mentioned if I hadn’t pre-emptively answered
