There were obvious nods to the League of Extraordinary Gentlemen but Monsterpiece Theatre by @tom_scioli was just SO MUCH fun. I'm so glad a sequel is on the way.

loved the art, the dialogue, and the wide range of characters.

this is a #ComicBookOfTheDay for sure.

Helen of Wyndham was nothing like I had expected and so much better than I had hoped. When @tomking.bsky.social is good, he really is among the best. The artwork by @bilquis.bsky.social is breathtakingly sublime. I can’t recommend this enough.

like with Peep Show or Love & Rockets, #Hepcats was one of my favorite indie comics at a time when there weren't enough indie comics. I just re-read the series and enjoyed it as much now as I did when it came out. I hate that this went unfinished.

You can imagine my disappointment when I clicked on this on my map and it did not say β€œThe Destroyer”

the audio and GM quality both need a good amount of work, but session 1 of Deathmatch Island was a HOOT. I can't wait for session 2.

I just saw this advert and it really took me back to being a kid. I never had these but this advert fired up my imagination in a way it's hard to explain. Memory is such a funny thing.

Anyone ever have these toys?

Parody of the classic chart of The Hero's Journey, labeled as The Fool's Errand. Divided into two sections: Unknown and Unknown. It is a great circle.

- Opportunity to gain
- Supernatural Prank
- Unheeded Advice
Here, the Fool passes from the Unknown into the Unknown
- Slip 'n' fall (intensification of error)
- Helper (who always lies)
- Old man (mistaken for wise)
- Seductions and Temptations
- Helper (who also always lies)
- CONFUSION - Hall of Mirrors - confrontation with the self
- Stumbling through the thorns
- The Unforgivable Misunderstanding
Passing from the Unknown back into the Unknown
- (Rejection of the Goddess)
- Coming home before he's supposed to

Distemper is a #TTRPG without classes or levels where characters are ordinary people trying to survive through darkly extraordinary times. Community rules allow PCs recruit Cohorts, Conscripts, or Converts and they rebuild in after the Dog Flu wiped out 90% of humanity

Pick wisely.

I will be releasing the Xero Sum Engine SRD as part of the Distemper Kickstarter so that groups can really kick the tires, and have just updated it to include/sharpen rules from recent playtesting. Now on to the layout, then on to rewriting the QuickStart with the updated rules

#TTRPGCommunity - I am running @evilhat.bsky.social’s gorgeous #DeathmatchIsland for the first time next week, has anyone run it and have any advice for me?

If I can figure out my OBS setup in time, I might also stream it…

set a year from today, characters in the Distemper TTRPG are ordinary people in extraordinary times

surviving in a world where 90% of mankind has been killed by the Dog flu means asking yourself, what am I prepared to do to survive?

the biggest threat is always other people
