I hear there's lots of new folk, so might be a good time to pass around this Mothership Creator starter pack again:

Please let me know if I'm missing any cons, or event details! I'm still working at it.

MeatCastle GameWare - Annual #3 is coming in next week's Missive! 6 TTRPG freebies all in one 24-page zine. I'll be taking pre-orders at that time as well for the physical print run (which will be super limited). Pre-orders will be open for two weeks and then I'll order prints and get them shipped!

Flatline on the Blocks has been such a fun project! I hadn’t written for Mothership in a while after writing Resonant so it was a good time to work with everybody. #osr www.backerkit.com/c/projects/s...

I am behind, but just listened to the Ansible Uplink episode with @unenthuser.bsky.social talking about WEG Star Wars and damn it was a good one. Love that system, even if the modules aren't to modern standards.

Hyped to have more of those coming later by the sounds of it.

Strong reminder that rights granted are rights that can be stripped. Just because we currently have a pretty favourable legal framework with regard to LGB rights, they aren't irrevocable. It's vital to understand the current attacks on trans rights as a stand-in for a broader attack on LGBQ rights.

Great pair of essays for thinking about writing anti-colonial ttrpgs and adventures.
My friend Habeeb made a blogpost a few days ago titled "the default dungeon is colonial", which prompted me to finally finish this blogpost.

"Anti-colonial Dungeon"

I guess I should finish my Anti-colonial OSR Tabletop RPG adventure/setting/game.

My complaint about Metroid Prime 4: it is not Jayquaysed, at all.

I'm not the only one dreaming in games, it seems, 😂
Brain at 4am: WAKE UP, you NEED
to write a game called "The Expense"
in which you play as an Accountant
in the Expanse, trying to balance the books
and get the crew to file timely expense reports.
This game will take 1 year to make and will
earn you literally tens of dollars.

This tool is pretty fun. Apparently I am very offline which is a great laugh.

Funny bit was my Top Posts list. The top three were for my birthday itch sale, the Twisting Unseen (premature) Pre-Launch, and a random, thoughtless post last week about Flatline development work.

Relevant today
Oh hey, I published this blog post yesterday about how to build a #MothershipRPG campaign based around a search and rescue ship trawling a few star systems for distress signals.

Totally my own initiative, and not for any other reason that will become apparent in a future Ansible Uplink episode.
Search & Rescue Mothership Campaign
Loads of Mothership distress signal adventures ping out in the void, so here's a way for folks to get those to table as a cohesive string o...
