Aaron Griffin You need to know how to run Dungeon World in order to run the quick play version (or be good at running PbtA system, at the very least), but you don’t need any additional rules. Check out the pdf of Battle Between the Worlds (it’s free), the SWvsM quick play is basially the same just with different characters. The regular version of the game uses the DW rules. Any other DW-related product is totally an optional thing.
