FOG OF WAR option (or just include it baseline like practically every other game of this style on the planet) to both improve performance for low-end machines (I really don't need the entire planet loading all at once when I'm in an outdoor area, just for the sake of screenshots) and to stop hidden areas and rooms that haven't been explored from popping up, which completely breaks immersion and the feeling of mystery.

I don't want to fall to bits 'cos of excess existential thought.
