General

Of the following under Metaphysics tab, which one unlocks the most features in the game? (new things to do or new features unlocked). Enlightenment Diplomacy Chronomancy Unicornmancy Carnivals Adjustment Bureau I was thinking Diplomacy because it unlocks Leviathans and things to do with the Blackcoin Stockmarket. But what about the others? Do they unlock anything? Especially whole branches of new stuff to do in the game.
