Mage: Fuzzy Set Theory
Because of the nature of the game, not every rule is going to work precisely the way that it looks like. Some rules are simply Not Applicable, and if they come up I am very likely to simply say “no, it doesn’t work like that.” However, my desire is that I’ll have how things do work set up in advance, so that if I have to nay-say something, I’ll be able to say why.
On the flipside, some things are just intended to be Weird and Confusing. Drugs are like that.
