Yes because there are some "puzzles" out there that rely on you knowing what Basil II had for breakfast on February 21, 1011. In a universe that didn't even have a Byzantine Empire. And missables, I hate missables. Especially the ones that involve going back to your home town when you've entered the final dungeon, but just entered because if you go into the next room that item is lost forever! Unless you want to play through the 80 hour game again.

But I never for physical puzzles though. I mean if they give me all the stuff I need to succeed in the game proper and I have to use a guide, I feel like I've lost.
