RotMG.com had used maps from my mapgen2 project. There are 2^33 possible maps. I didn't know which seeds they used. I figured … let me just try them all … how hard could it be? ;----)

Goodnight Universe continues to express its creators’ obsession with lost time first explored in Before Your Eyes. It’s weirder, but similarly moving and well worth seeing it through.

Could the next trend in spam - annoy a million people with something nobody wants to play - reduce trust in games/Steam/etc. - just to get a few people to give them money. Just has to make slightly more money than it costs.
But none of it will be driven by people who enjoy making or playing games.

the idea that lots of gamedevs are secretly using ai is booster bullshit
what on earth would I use genAI tools for? Coming up with ideas? Writing? It’s shit at those
making 3D models? Coding stuff? It’s shit at that too
oh but it’s faster maybe? Did I mention it’s shit at things?

We don't use generative AI at either Minor Key Games or Question. Partly on principle, and partly because we're really good at what we do.
We don’t use generative AI at Strange Scaffold and I can confirm that a *lot* of other studios are not—whether indie or AAA.

In case anyone ever asks, I *have* written a material generator and a music generator for Eldritch 2, but that's not AI.

I would agree, and also say that proc gen *is* a form of AI, it's just that genAI has now become interchangeable with the term and nuance has been lost despite the fact that creative computing and algorithmic art has existed for decades
A big reason proc gen feels so different to AI in spite of superficial similarities is exactly this!!
Proc Gen systems reflect the interests and creative preferences of the tool makers, whereas AI is catch-all sludge that reflects no specific point of view. It’s not remotely the same!

to put this another way, people turn to AI because they don't want to be wrong
assuming it's even correct, until not knowing affects us nothing in us will change. if AI gets it right, we stay wrong, like being able to misspell a word close enough for spell check, we'll fumble it the same next time

glad to see pushback
learning and skill growth happen when what we knew going into a problem weren't enough to answer and move on. AI flatters you to feel you know enough to get an answer out (often not right, but even if it were!), user doesn't have to become more capable, becomes dependent on it.
