New York’s hottest #ttrpg is Arrhenius. IT. HAS. EVERYTHING.
✅Exploding dice
✅Psychotropic eel poop
✅Feral AI
✅Human snowpants
(What’s “human snowpants”?)
It’s that thing of when a robot decides it isn’t human enough so it skins you and wears it out on the glaciers.

I have been waiting for this all summer! Session 0 of a new collection of #Arrhenius#actualplay#ttrpg podcasts by @diceydiscourse.bsky.social.
Episode 1 is all about character creation; so if you’ve been curious about the game, this is a great place to get an overview of characters, lore & more!
AND LIFT-OFF!
We're ready to kick Season 2 of Dicey Discourse into high gear!
More collabs, more indie games and perhaps a surprise or two!
We're coming in hot (or cold as it were) with the Icecore indie RPG ARRHENIUS! @arrhenius.bsky.sociallinktr.ee/diceydiscourse
My #TTRPG “Arrhenius” is getting the #ActualPlay treatment from the wonderful folks over at @diceydiscourse.bsky.social. Ep 1 is up now in which they create their characters and begin to dive into the world’s lore….

It’s #SelfPromoSaturday! If you’re into indie TTRPGs and subzero temps, I’ve released a new narrative survival game set 100,000 years in the far future during the next Ice Age.
“Arrhenius” is available online as a core rulebook, but also as a free Quick Start Guide.

Have any questions about Arrhenius as an #indie#ttrpg? Mechanics? Setting? Beastiary? Gear? Available resources the game?
Let me know! I’m happy to answer any and all questions! #AMA

"Fandoms used to be full of nice ppl before covid and then all the bullies and popular kids joined" is literally an "the earth is flat" tier false belief to me
What's your "origin" video game?
Most gamers have a lot of favorite games, sure, but there's always one that basically 𝘥𝘦𝘧𝘪𝘯𝘦𝘴 you.
I'm talking about the game that flipped that little switch in your brain and made into a life-long gamer.
So, which game is 𝙮𝙤𝙪𝙧𝙨?
There’s an Actual Play coming soon of #Arrhenius from @diceydiscourse.bsky.social. I don’t know anything about their game and I’m anxious to hear how it all went!
Fucking AI. I did a Google search this morning to see if anyone had reviewed Arrhenius (spoiler alert: not yet). I get this AI summary that says people dig the world building but some find the terminology difficult to get into at first and that makes it clunky.
Disappointed to hear that, I went to the linked Reddit thread to see what people were saying. Read through the whole long thread, and guess what?
No one mentions Arrhenius at all. So, turns out Google is just baselessly hallucinating criticisms of my book. That's fun! Just what a new author needs.
Hey! Check it out! #Arrhenius is now up on the @ttrpgwiki.bsky.social.
I know Arrhenius isn't a rules lite game, so no surprise on the Complexity score. But check out those nice Accessibility and Runnability scores!

It’s the weekend! Who has a TTRPG game planned?
I’m going to continue running my playtest group through a new #Arrhenius dungeon I started with them last session.
Here’s hoping everyone’s games all go well. And as always: if you’re playing Arrhenius, let me know!
If you see this, post a monster.
This is a giganath. It lives in giant subterrean lakes. Its poop is harvested by enterprising dorrem for sale on the black market due to its psychotropic qualities.

4. Fungus: When I was part of 5e D&D's playtesting, I played a halfling rogue named Fungus. Fungus was disgusting, crude, and anti-social. Fungus lived in sewers that were so damp that mushrooms were growing on Fungus' clothes. Fungus was also a coward who only spoke in 3rd person. Fungus was fun.
5. Toof: Toof was a half-giant with a serious history of traumatic brain injury. Half of his skull was missing. As a result of his injury, Toof was convinced he was the tooth fairy and would roam the world, his sack of teeth in tow. If he saw you had bad dental hygene, Toof would beat you to death.
2. Claire duLac, a cleric of Deneir. Claire was a kind, jovial girl who loved books and was far too naive for the nastiness of Barovia when she got whisked away to Ravenloft. She and Strahd fell in love and while Claire whithered on the vine, she slowly became the reincarnation of Strahd's dead wife
3. Rapp Varlet, a bard in the 1st ever AirDnD game my friends and I played. Also my first ever 2e DnD character. Rapp was scrappy and quick-witted (probably more quick-witted than me) and he survived a delve into a lich's pyramid. His main weapon was an ironwood lute that he'd clonk people with.
1. To start off: Wex Spritsail, the D&D 4e ranger that I played in my longest campaign. Wex was awkward and distrustful of people because he was on the run from the law after being accused of a crime he didn't commit. Wex had a wonderful story arc and both he and I made lifelong friends.

Well, the Ennie Award nominees are out and Arrhenius didn’t get any nods. Boo. Maybe my next couple ideas might have more reach….
Congrats to all of the nominees!
What's an under-represented TTRPG setting? And do you know of any RPGs that do it (and hopefully well)?
Off the top of my head
1. There isn't a lot of super-far future stuff, but Arrhenius does that setting.
2. Far past. I only know or Würm that does the end of the last Ice Age
See a robot, post a robot.
This is a new piece by Altay Davletov for the first expansion of the #Arrhenius#ttrpg called "Fahjē's Guide to Gear."
Apparently even for ozzits, trying to get a clear signal is still a whole thing in the year 100,000.
