You guys should check out Tunic!

It’s a cute zeldaish adventure where a manual a a core part of the Gameplay loop. Basicly you find pages of the manual ingame as you progress and learn about it this way. And the manual looks freaking georgous. A pure love letter to exactly that time. But be beware that Tunic is a knowledge based game. So any information might spoil something for you. Please inform yourself with caution.

If you enjoyed the game you can even order the manual as a physical prop as official march.
