Libraries and museums that have info on planets and clues (audio logs, hidden words, and riddles) on how to find weapons and armor. This would weed out the weak and lazy because they wouldn't have have the willpower to decode clues in order to unlock awesome weapons and armor. You could solve mysteries like Indiana Jones.
Please share ideas below.

I would like museums that tell us about legends and myths of the wastelands of earth or other planets, not only it could expand the lore but they could actually exist and players find such things in the middle of battle.
