Mage: The Ascension

White Wolf's game, in which magic works to the degree that it does not contradict what everyone believes — and a magician who works too openly is punished by reality itself, through the consensus of ordinary minds.

The bridge to ⊞ the reality tunnel, and a rules system that is an argument. Consensus reality as an active, enforcing thing is Robert Anton Wilson's territory turned into a mechanic — and it is one of the few cases in this wing where a game improved on the material it borrowed by making the doctrine into a die roll. The doctrine must be the mechanic is a rule this app runs on, and it is worth noting who was doing it in 1993.
