I was able to figure out that I needed to light a deku stick on fire and roll over cobwebs to get to the floor below in Ocarina just fine at 7 years old.

And that's not even touching on the Water Temple.

People, especially game devs, underestimate children.

Some people can use help on puzzles, sure, and I don't hate when a game gives some hints or guidance there, but it can be a bit egregious (God of War was terrible with this, and I heard Ragnarok was even worse). What really drives me up the wall is the constant hectoring by npcs or even the player character to get to the next mission checkpoint, often in open-world games where a lot of the fun of the game is exploring outside of the narrow mission path. It's like devs have such little faith in their game that they want the player to just finish it as soon as possible and not investigate it too much.

I'm replaying RDR2 and a huge part of the enjoyment of that game is just going off and hunting or running into random encounters. For the most part, the player can just go off doing their own thing, ignoring the plot entirely. Can you imagine how awful it would be if Arthur was constantly muttering about how he should be on his way to this point or another, just to progress the story?
