Fable 5.2 one-shotted my nephew's dream game

> I must admit I never tested this with Opus 5.5, so I'm not sure whether this was possible before Fable 5.2 rolled around. Since somewhere around Opus 4+ it's been really good enough to do these things, but 4.6 was the most pivotal version since a 1 million token context window can allow a model to fit so much "in its head" basically.

This is both cute but also a bit sad in terms of game stylization, I guess these generic AI designs could become so normal to the youth that in the next 10-20 years it just appears everywhere

I appreciate the token breakdown, but how much would this cost in money? Chatgpt estimated $400 to $600, but I don't have enough knowledge of token pricing to know if that's accurate at all.

My dream game is a high fidelity universe as detailed as GTA 6 or Red Dead Redemption 2 and as expansive as No Mans Sky.

Reminds me a bit of Little Fighter 2.

I tried the game and in some seconds noticed I can kick the enemies forever if I put them close to the left corner. I'm feeling now that I'm the AI exploiting bugs.

My dad asked recently if AI is good enough to create something like DX Ball - a breakout style game we used to play a lot. Opus 5.5: https://claude.ai/artifact/UuT7P936dU1XoPByYZ7xyD Fable 5.2: https://claude.ai/artifact/UszKFvuonWAT5psjMttAEg There are some areas in which Fable is clearly better but subjectively the Opus 5.5 version feels more fun. Both are one shots, Opus 5.5 was done a few weeks ago before they added "guardrails" around recreating games. Fable 5.2 changed some game mechanics despite my prompt asking for them to be the same as original game.

I’m waiting until I can give AI a link to a Macintosh garden game and ask it to be reimplemented in the web browser.

It's not as good as Street Hassle on the Commodore 64. AGI.

does anyone else worry about future generations growing up on ai slop? because i wasn't until reading this post. now i'm terrified.

I noticed this recently with Opus 5.5: you can tell it to "make this more fun" for a game project and it... makes it more fun. It's neat (if unsurprising) that Fable 5.2 has this ability as well. My loose testing shows other models aren't quite as good at this yet. Here's the prompt "Build a mobile-friendly three.js game where a mouse has to hide from a cat" by Opus 5.5 Extra - https://claude.ai/artifact/RRyEndXLSPQbcig3BgzgCZ - and by GPT-6 Extra High: https://squeak-and-seek-mouse-1027.simonw.chatgpt.site/ - the Claude one is a better game, even though they look very similar at first glance. Update: took it about 40 minutes but here's Fable 5.2 Extra's attempt at the same prompt: https://claude.ai/artifact/Agsqbng2MnkTPAU67it87o I wrote about Opus 5.5's sense of fun in more detail here: https://simonwillison.net/2026/Oct/28/vibe-game-development/

I quickly dove into the game and then got lost as I couldn't exit and had to spam keyboard to see the controls. The menu refers to "Punch" but it wasn't obvious what key that is (and it wasn't "p"!). I see that ENTER pauses, but may I suggest also making ESC and/or P pause. And then the pause screen showing or linking the keyboard controls and an exit path. (Caveat: I'm not much of a gamer so maybe the current controls are standard? Anyway, I feel like it could be more inviting to casuals with something like the above.)

Ignoring all the positives & negatives surrounding this technology for a minute, this is an amazing outcome for the kids.

Is Pudding the dog (unlocked after beating the first boss) supposed to shrink anytime it jumps? I guess even Claude-turned-world-class-game-developer isn't immune to bugs. ;) Honestly, setting all the oft-cited AI caveats aside, the end result is cute and perfectly serviceable as a game for the kids. I can't imagine how stoked they were about playing it.

What does one-shot mean in this context? Aiden (the main character)'s walk cycle is kind of a mess and its also the animation that a player is going to see all the time. It appears to be eight frames, but after taking a closer look, I found that they don't seem to be consistent [1]. Using ControlNets and various other strategies, you can definitely build out a "nominally acceptable" walk cycle [2], but you still have to do some manual work.

I want to ask this as politely as possible, because you set out to do something nice for your nephew and he had a good birthday. The first thing I felt when I saw this post was concern on the impact of this type of thing on the mental development of children. For example developing specific skills like drawing, and general emotional skills like concentration and learning to be happy with their own skill level. I respect it was a light post where your aim was probably to highlight something fun, but I couldn't see any note of what you thought about it. What do you think about that? What do his parents think?

AI pixel art still looks awful I see

My dream game is Tetris. I would be concerned if an LLM couldn’t ahem “one-shot” that.

People are really out there naming their dog Doggo, huh?
