Tomorrow at 2 PM ET, we're kicking off the Epic AI MegaJam with a livestream!

Join us for the official theme reveal and a hands-on walkthrough of how to set up MCP in Unreal Engine 5.9 Preview to help you get ready to build. https://t.co/cuz6sz9hgJ

Steam’s AI disclosure system is failing both developers and players. The platform provides almost no clear education on what the label actually means specifically that limited LLM use for coding is generally outside the scope of required disclosure under their own Content Survey rules.

As a result, when studios do disclose in good faith, they are often punished with review bombs, cancellations, and performative outrage from people who do not understand the distinction. The food ingredient list argument no longer holds: even when the information is provided, it is routinely misinterpreted and weaponized rather than used for informed decisions.

Under these conditions, refusing to disclose has become the rational path for many developers. Steam controls approximately 74–75% of the global PC digital game distribution market by revenue. How can games win under these conditions??

Option 1) build a factory that outputs infinite Nobel-level knowledge on tap that could save lives and ascend humanity to the next level

Option 2) preserve abandoned concrete parking lot eyesore

They chose option 2. 🤦🏻‍♂️

@TimSweeneyEpic 5.9 is already awesome for me. It cut my fully automated testing time from 20-25 minutes to 1-2 minutes.

It's a new age of game development! This is the Unreal Engine 5.9 preview, consisting of huge improvements to AI acceleration ported from unfinished Unreal Engine 6, plus entirely new support for play inside web browsers.

[William Faucher @WillFaucherVFX]

Ok so. #UnrealEngine 5.9 is pretty sick. You can build a web browser version of your game, so I built EasyWaterscape's playable demo... and it runs at a rock solid 60fps, @ high settings, in chrome, at 4586x2372.

What the heck?

So, what would actually happen if Apple decided to allow users the freedom to download iPhone apps directly from developers’ websites or other app stores?

First off, you as a user, normie or consumer, you could save money on in-app purchases by avoiding fees that can reach 30%. You would also have much more variety of apps to download from that you never could.

Even the developers who love the App Store and prefer to stay on the AppStore would benefit. But how!?

Apple would have to compete to keep their business, potentially lowering fees, improving policies, and making life easier for developers. Aka treating you better as we deserved better.

But instead of discussing these benefits, the conversation always comes back to the same excuses: “security” and “it’s Apple’s platform.”

[wyfi @wyyfi]

You know why it’s painful though, right? It’s because they don’t need to make it better. That’s what a monopoly is, and if Apple allowed competition, then your experience would definitely have to get better as you know, like an actual business, they would have to compete. I talk about it more here:

Take Two says: "Pre-orders for Grand Theft Auto VI are tracking far in excess of our initial expectations, and we know that the numbers will speak for themselves soon enough."

AI game development is exploding on Roblox:

- An growing share of top games were launched in the last 90 days
- Roblox MCP daily users are exploding
- An increasing fraction of game development time is spent using AI
- Asset uploads are shooting up

In other words, people are using AI to make games, and other people are actually playing them.

UE 5.9 preview 1 now ships with a new plugin I worked on called AnimGenOffline (name might change) which allows you to guide animations at high level and use AI to generate the actual frames. This integrates that functionality into Sequencer.

As initial plugin into this system we integrated NVidia's Kimodo. But the system itself is not limited to this. Basically any algo that generates pose data over time can integrate with it.

You can draw splines and make characters follow them, type a style in text, set target key poses at certain frames, etc. You can pose your character directly with Control Rig and retargeting is all handled automatically.

You can also type: "Use Kimodo to generate an animation of a drunk person walking forward and save it as an Animation Sequence asset in /Game/Anims/DrunkWalk".

Weights still have to be downloaded from Huggingface (goes automatically after creating an account and read-only token etc). We're working on making that easier too.

It can run on basically any PC, but for fastest generation you need a Geforce 3xxx series or better. And probably Windows only for now, although I haven't tried on other platforms yet.

This is just the start of course!

Worked on this with @FredNilsson
Will show some videos soonish, or share some community videos.

@VistaLargaGames Indies are more vulnerable to pressure campaigns by bullies who attempt to stoke hatred for them among their own communities online. That's the difference.

@DiscussingFilm I miss Vangelis.

@djraz369 Perhaps Apple hasn't eliminated its UTB process where developers lobby them to remove competing apps based on arguments around interpretation of vague Apple policies.

[David Razmadze @djraz369]

I posted on Reddit a screenshot of my apps MRR and the next week or 2 my entire Apple Developer account of 6+ years was terminated.

Be really careful with sharing what is working for you.

It could have been something else but me posting on reddit is in the top 3 of the theories on why Apple terminated my developer account

My other theory is I was submitting too many app updates in a short amount of time (post on my page)

I'm in the Epic AI MegaJam 🎮

Theme drops Nov 11, 11am PT / 2pm ET, on the @UnrealEngine kickoff stream. I'll be live to hear it with you and start brainstorming.

Then 4 days building a game in UE5 with my team, streaming as much as I can.

Come hang out
