Yeah, it just depends on what I'm looking up and the game.
I'm playing Diablo 4, and I looked up a guide on a certain build before starting.
So now I have a clear goal and I know how to farm the equipment instead of not having a clue what to aim for, or trying to find items aimlessly for hours.
If I look something up, it's usually things that could cause me to not have fun if I miss it in my playthrough.
