Worlds Funsome and Free: Understanding Open Role-Play Adventure

You've heard of FKR? Its like extreme OSR, which is a kind of RPG, but I prefer to call it ORPA. So many acronyms! This here's a brief and informal explanation of all that. It comes down to running tabletop role-playing adventures without a rulebook -- a "rule-less rulebook" you might call it. No sophisticated formating, just black-and-white words on a page getting the ideas across directly, preferably to be printed out and experienced as hard-copy for tactile and focused consideration. 

"At its most essential, Open Role-Play Adventure – ORPA for short – is tabletop role-playing achieved primarily through open discussion and impromptu judgments, rather than through recourse to pre-codified rule systems, as it was done in the earliest days of the medium before such systems existed. Very often this style of play prioritizes the evocation of a world as a believably living place, experienced vividly through description and collaboration – representational game mechanics used only as discretionary tools in the cause of that, not as the focus of play in themselves."
