Given the other discussion talking about "tech before games" and design issues inherent in Rust, you are correct; I am very unlikely to pick up this game engine.
> The dominant conclusion of that other threat, at least as far as I've seen, is one that I concur with — namely, that Rust is absolutely not good for writing game logic, but is probably quite good for writing game engines, and this engine seems like a step towards making that distinction, since it doesn't work like a framework, where you write your game logic in Rust and compile it with the game engine into a single static binary, you instead have the game engine be a separate executable that you then load your game logic as plugins into. The plugins are still currently written in rust, but I'm sure you can see how that could change.
But to each your own! I'd certainly recommend Godot or Unreal over any Rust engine every day of the week as well, just like I use SDL2, OpenGL, and imGUI over pure Rust solutions even in my own Rust game engine work.
