You say that, but there is a lot more overlap in communities than you are giving credit. Steven Lumpkin, one of the co-authors to the influentially oft-cited Principia Apocrypha: Principles of Old School RPGs, or, A New OSR Primer and a big fan of West Marches campaigns is a major fan of Blades in the Dark and Band of Blades. John Harper also wrote an even more OSR inspired version of Dungeon World that tried to imagine the precursor OD&D form of the game: i.e., World of Dungeons. You'll likely find that there are a lot of people in the various "story/narrative" community that also have their feet dipped in the OSR communities as well.I will listen, but just worth pointing out that the person who wrote Blades in the Dark (and to be not knocking that game at all, as it is on my list of games to pick up), is probably going to have a very different take on sandbox than people in the OSR and where I am coming from.
Edit: @Fenris-77 beat me by seconds to the punch.
