Dispatch from fighting game land: 2XKO is out in Closed Beta today, which means for some people it exists forever, and for everyone else it will exist forever soon, and I simply cannot believe it.
I love this game, I am very grateful I got to spend a good chunk of my life making it.

Burned my brain out playing 2XKO today - a special kind of melt I've only really had from long sets of tag fighters. Oh shit it works. 🙏

Man, games hit different when you get to play them with people who aren't making them. I had SO much fun playing ranked duos in 2XKO today. Can't wait til we get the rest of the world in there.

When I joined Spry Fox 12 years ago, I worked on Road Not Taken, a roguelike narrative puzzle adventure, a game I loved. Blue Prince is also a roguelike narrative puzzle adventure, somehow managing to have absolutely nothing in common with Road Not Taken. 👏

You could show me any ten seconds of Severance at any time of my life in any fictional universe where I've never heard of Severance and I'd instantly know it's my favorite show in every universe

Hellloooooo if you are going to GDC and are a systems designer (or aspiring to be one), I'd like to recommend registering for this. Free, only about a block from the Moscone, and usually a really good mix of people (if I don't say so myself).
Do you design game systems, even a little as a treat? Will you also be at GDC this year? Gosh do I have the event for you. Our tenth annual GDC Systems Design meetup. Wednesday, March 19th at noon. Register, chat, enjoy! lu.ma/ileesdw6

Behind the times, but one of the greats of is BACK. 868-HACK is easily one of my favorite Roguelites, _certainly_ my favorite Broughlike. What a purified essence of game

Was there a vibe shift? I'm pretty sure The Ship of Theseus isn't a paradox anymore. It's just obviously, uncontroversially the same ship.

Ridiculously insightful, nuanced, clear-eyed take on Trump's coming autocracy. Reshaped how I think about what's happening and what's going to happen. Not in a good way. But getting clear does feel empowering.

Lessons from today's prototyping meetup #gamedesign
1. Build the middle of your game first. Can you play your own game for 40-60 minutes? Then figure out how to teach that. Tutorials reveal the known fun, they don't find the fun.
