At a scale of 1k planets you’re going to have to rely on reused assets and procedural generation. At which point people not into procedural generation say that it’s “repetitive”. Especially if you only gen once for everyone and not each run lol.

AI generation of assets and code will theoretically eventually resolve this, but that’s quite a ways off. They’re not even usable for such with human assistance yet. And if you have ai generating the content, it’s not really a human team making that stuff lol.
