Watching content creatures I find is useful. Especially to check if others are making the same assumptions or having the same experiences.

For example, there might be some content that I thought was very dull/drawn out. Rather than complain here, I’ll check what someone else did.

More often than not, there was a gimmick that I just didn’t notice to speed it up, or some misunderstanding I had about what to do.

Basically a good way to check that the problem I was having was a “me” problem.

Secondly, it is useful to rewatch certain parts of the game in their full context for lore purposes.
