hi everyone! i'll be taking a break until the end of the year. expect this month's patreon essay (THE GAME OF THE BALL) to still come out for paying members, and underside playtest to continue development, but there won't be any paid content on here in december so i'll be pausing billing until january 6th. have a nice w...

wip playbook art for THE CHOSEN ONE, by HZZRD666
a while ago i was having a chat with a friend about how different modes of play can bring you to different times on your life. this touched on something i've thought about a few times, that the OSR is...

On a summer’s day an alien lands in Buenos Aires. He steps out of his spaceship, conical and rough like a snail’s shell, and speaks through a glistening translation bubble. He says, to the bewildered boy in front of him, “I have heard of your great game, fútbol, and I want to see it.”
So the boy nods, because he is an ...

hi everyone! the first month of playtesting has been extremely fruitful, and i put out the playtest's first revision a few days ago--i posted about it in the playtest discord but not everyone keeping tabs on underside is there so i figure i should post the changelog here too:

hi everyone. thank you so so so much for your patience and support all this time. i'm beyond excited to announce that underside's first playtest release is finally here!

so, with the underside beta playtest release on the horizon is less than 30 days, most of the work is going into tables and lists: stuff that you pick at character creation and advancement. one of these is the quirks, a set of character traits based on tarot cards that make huge deicsions about who your character is on your beh...

sorry, it's been a while. i think that weekly patreon posts, at least while it's not my primary form of income, aren't really feasible for me, and i burned myself out trying to do them. here's the new thing: there'll be a patreon post at least once a month, either a dev diary or another piece of writing by me. if there's more than that, there'll...

those of you who have been keyed in to underside's development will know there's been some pretty notable schedule slip. i've got a lot of shit going on in my life! so instead of promising any specific date for the full underside release or the combat-ready playtest, here's a comprehensive overview of everything that's done and...

i love worm. underside only exists because of worm -- it started life as capes in the dark, a hack of blades in the dark that made it about worm. most people on this patreon, i would wager, are here because they love worm! but the longer i and citizen abel work on the game, the more we're con...

there are a lot of ways you can conceptualize TTRPGS. usually i use the lens of 'collaborative storytelling' but for this post i am going to say that playing TTRPGs is just playing pretend. now if you imagine a big dragon, and a guy hitting him with a sword, that's all well and good. you can picture it in your head however you want to. maybe the...

TTRPGS ARE AN ABSTRACTION OF AN ABSTRACTION. A STORY IS ALREADY AN ABSTRACTION OF REALITY AND THE TOOLS AND RULES THAT A TTRPG GIVES YOU TO PLAY WITH ARE ABSTRACTIONS OF THAT STORY. EVERY WORD USED SHOULD COUNT. YOU DO NOT GET A HOCKEY STICK WITH YOUR CHESS SET. WHAT KIND OF STORIES ARE WE TELLING THAT THE 'STRENGTH' OF MY CHARACTER IS ONE...

so that's approaches sorted out. but approaches are only half the battle. in underside, when you do something dangerous and you're not sure you'll succeed, you make a conflict roll. this is the game's basic resolution tool, and your relevant attributes decide how many dice you roll. your approach will always be part of ...

so when figuring out what approaches to put into underside, citizen abel and i talked for a while about what we actually wanted out of them. in the end, to help guide the choices, we split the eight approaches across four axes, creating matching opposite pairs that offered an interesting range of characterisations. these axes don't have...

the first edition of underside, capes in the dark, had a stat system, mostly inherited from the 'official' (made by the creator) worm ttrpg weaverdice. ultimately, it didn't suit the game very well -- and i think D&D-style stat systems (strength, intelligence, dexterity, etc) rarely do, honestly. i'm a strong belie...

not, like, as people. i've been a GM for many games in my time. i don't like the role as it is widely understood--i especially don't like dungeons and dragons' 'DM', because i think it encapsulates what i don't like about the play role most of all, but in general i don't like GMs. & the reason i don't like them is that there is in t...

across basically all superhero media but especially the darker, grittier stuff that underside is based on, a crucial part of any hero or villain team is the violent fracturing over moral faultlines, over who gets to be in charge, over whose plan to follow. but player-on-player conflict is always a tough thing to handle, and esp...
