Just so everyone who reads this understands; despite the criticism in this comment, it's being incredibly charitable to LLMs in the context of making games. They're not particularly good at it and you wouldn't want most of the code they write in your game and especially not in the underpinnings of your game.

It's not true as a general rule that they could give you correct small code snippets five years ago; I had frontier models not even understanding enough of the OpenGL API to make separate framebuffers correctly. I asked this as a test and the resulting recommended code would of course compile, but leave someone who didn't already know the correct way to do it staring at a black screen and potentially spending the next hour debugging that.

If you think you're somehow going to make an actual game worthy of people's time with LLMs, you are almost certainly mistaken. Not only because it'll be a complete, unworkable mess with really bad fundamentals, but also because if you're vibecoding the actual technical part you probably also think game design is just about "having ideas" or something else that's really reductive and incorrect.
