Into the Pit - Hacking Dungeons and Dragons 5E and rulings not rules? (R)

A podcast originally aired as episode 370, wherein I attempt to clarify design concepts for my DnD 5E Spike Hack and also ask if the OSR mantra "rulings not rules" is still applicable when making distinctions between DnD of old and the current edition of today? Big thanks to Barney Dicker (Loco Ludos) and Jason Connerley (Nerd's RPG Variety Cast) for their called in contributions.
