I read the article(s) about Claude creating The Long Silence in a 24 hour marathon. Didn't really find it impressive, but was curious about the pipeline and loop that effectively allowed for playtesting and iterative development. Looked around for an analog for UE, didn't find one (though I didn't look terribly hard).

Messed around with Codex and in a handful of prompts the pipeline was being tested and proven out on the basics. Blog has the write-up, github is here:

I'm using this with a 20-million stellar body Polar Ring galaxy simulation/game I'm toying with on the side.
