My timeline is flooded with GPT-6 Astra generations.
We saw something similar earlier this year when Google shipped Project Genie on Jan 30 and the engine names got taken apart, with $U down more than 20% in a single day and $RBLX and $TTWO going with it. The fear was that if a model can generate a playable world, nobody needs an engine.
The difference now is that the models are working with the engines. OpenAI published a Playco case study on Sept 3 where an agentic IDE plugs directly into Unity and Godot, and they got three playable prototypes off one grey box with 50% fewer manual fixes than the previous model.
I don't think AI replaces game engines, at least not yet, because generating a world and running one are separate problems
> state that persists across sessions
> physics that behave the same way twice
> bugs you can actually reproduce
> players staying in sync across devices
So while these names keep getting lumped in with the software stocks getting commoditized, I think there could be an opportunity here.
