Spelljammer creator and writer, Jeff Grubb, drops in on the podcast today. We talk about Jeff's career and how came to work at TSR.  We discuss the classic setting of Spelljammer and its genesis. Plus, Jeff was also the lead designer on the Marvel Superheroes role-playing game. The Marvel Superheroes RPG was a very important game in my development as a game master and a role-player. Currently, Jeff works for Amazon developing video games.
