For those who played the new Marathon and wished that it wasn't a PvP game:

If you love the new cyber-brainsmash aesthetic, play the Cicadamata demo immediately.

And if you want a more old-school Marathon, Supplice. Now.

Look, I get that dentists are *supposed* to care about your teeth, but why do so many of them seem appalled that your teeth are used for chewing food?

"YOU DID WHAT? WITH your WHAT?! You don't unhinge your jaw and swallow food whole like we do?!"

It's looking more like "automated" systems and "AI agents" are actually run by humans and I'm not sure if that's worse or not

Still open and got bills to pay! It doesn't have to be anything big! Even if you need an hour or something, that's fine! I'm very affordable, I promise!

I remember I was at GDC with you years ago touring the expo floor, and I was feeling sad and mused aloud, "Look at all this tech - are we wrong for doing everything ourselves, Sos? Do we need this stuff to make compelling work?"

And you responded, "Nah, it is all shit."

I'll never forget that.

30 years ago (29 Jan 1996), I uploaded Duke3D v1.0 shareware to Software Creations, and a legend was unleashed on the world. This pic is George Broussard pointing to said upload happening.

Was a super fun game to work on - lots of happy memories. #AlwaysBetonDuke

Microsoft being cavalier with their "production ready" code makes me feel a lot better about all the code I've put in production over the years
