My guess is that existing scripting languages don't mesh well with all the parallelized staged simulation, entity content systems, and lack of tracing GC that game engines like Unreal tend to have. I don't know much about Verse but looking at the preview I already see a type called a type called `<latent>` (async Promise?) and a `race` keyword (seems like a built-in `await Promise.all`?). I bet building these directly into the language fixes much impedance mismatch.
