Neat! I write a lot of C++ plugins that are used in both Unreal and Unity. I like to think of them as "side loading". They can do whatever they want, however they want. The API surface that interacts with either engine is pretty minimal. I think "use Unreal as a renderer" is underrated. You could imagine writing your full simulation logic independent of the AActor framework and then using Unreal just for rendering. For a client/server game the server might not use Unreal at all! I'm not sure how valuable it is to use Rust but also use Unreal's framework and blueprints. Bevy + Unreal is a pretty fascinating combo and how much lifting is done by each side can be done in lots of ways.
