RAI
RAI, the acronym of "Rules As Intended", is any unofficial attempt by the gaming community when to figure out what the game developers "meant" when they wrote a rule. This is in contrast to Rules as Written.
RAI usually comes up when a rule in a game is either impossible to obey, or seems completely at odds with other aspects of the game. RAI by its nature encompasses a more diverse array of interpretations than RAW, inevitably leading to more skub.
