I totally forgot the bananas panel we are doing at NYCC this year.
To fit the horror theme for the show, @systemmastery.bsky.social @gurglespasm.bsky.social and I are going to do a Worldbuilding panel where we create new elder gods and then perform a ritual to summon one.

Taking a seven year old on any walk is the exact same experience as an old MMO escort quest. They walk painfully slowly and every fifteen seconds you realize you lost sight of them because they pathed into an enemy encampment (stall that sells $27 bubble wands).

Hi everyone! Sorry the episode was late! Jef (me!) has been going through a lot of family stuff recently and it's been tough, but hey, who isn't going through tough stuff right now, right? Anyway, I'm posting the episodes again here tonight, and I'm gonna try harder to keep doing that later, too.

And you know? I've gotta give it up to the old standbys I may not listen to all the time but ALWAYS have what I need - Jef & Jon at @systemmastery.bsky.social. That podcast is a literal treasure trove of content for all kinds of systems, but especially ones that never held the public eye for long.
