Jen did such an amazing job! Was happy to get @aurahack.ca's jacket in there, as well.
New portrait commission finished! Thank you so much @yourgmjack.itch.io for the great mix of direction and creative freedom in this piece, and for your incredible kindness and patience <3

The full version of COMMONWEALTH is out now! I played through a few seasons using the playtest rules and had a great time, so I highly recommend checking it out if you're even a little bit interested in challenging your friends to duels.
COMMONWEALTH is OUT NOW.

It is a "far-future social climbing simulation" inspired by En Garde!, The Book of the New Sun, and Barry Lyndon.

@nictringali.bsky.social did the layout and graphic design and the cover and interior art is from @amandalee.bsky.social

I regret to inform7 you ma'am but your son is dead. Your son is found in the Grey Hallway. The description of your son is "a poor soul who died in these hallowed halls." The son is wearing a backpack. The backpack is openable and closed.

This list is ridiculous, there's no mention at all of Kriz Paraz or Jaff Lafferty, and yet somehow Todd Bonzalez makes it despite having an atrocious season in High A

it's true, but i think a rice cooker and an electric kettle are pretty outsized pieces of the pie chart
Everybody has two kitchen appliances that will change their life. The problem is, they're different for everybody.

Whether you’re hitting the road today to take advantage of the Corolla Hybrid LE’s 50 MPG fuel efficiency, or using the legendary Highlander’s 16 cubic feet of cargo space to its fullest, I wish you and yours a very merry Toyotathon!

they didn't need AI to make Silksong, it just needed some deeply insane guys to have a blank check for living expenses until their next thing was done, I think we should try doing more of that instead

I head back into the solo gaming mines with a playthrough of Hardcase by @keftiu.bsky.social! There are lots of footnotes for folks who've maybe never GMed a solo game for themselves before.

Oh, and I have no memory where the handle "37th Parallel" came from.

A final reminder that my giant summary of #over/under exists before the game ends and I do one last update that adds some of the Secret knowledge I've accrued over the last month.
