alt Hacker NewsGame engines are typically in two languages, one for the engine itself and one for scripting. That even goes for Unity: in Unity, C# is a significantly more powerful than average scripting language (for lack of a better term), but the engine itself is still C++.
That's not to say that you couldn't write a commercial game engine with something like C# that stands shoulder-to-shoulder with unity and unreal, but it doesn't seem like anyone has attempted to do so. Maybe it's the decompilation fear.
Also, it would continue to make sense to use a scripting language alongside Rust.

As someone who has almost no familiarity with game engines, it seems the success of this port was largely possible due to a comprehensive test suite written in a runtime agnostic way. What might be the equivalent test suite implementation required to successfully port a game engine to another language?
UE 5 doesn’t come with a scripting language even though there is blueprints which a node editor easy enough to be used by non dev. Studios like embark (The Finals, ARC Raiders) have been successful integrated AngelScript in UE 5 and use it in these games. UE 6 will see the appearance of Verse: the scripting language used for Fortnite (and the end of blueprint at some point). At first I was sad to see yet another language but it is worth looking at the doc to see why and how it makes a lot of sense.

Stride should mostly fit the bill: https://github.com/stride3d/stride

Even the physics engine they use is in C#: https://github.com/bepu/bepuphysics2
Not a very popular game engine (never got the attention that the likes of Godot did), but it's nice to work with! It’s up there with Stride in regards to the “indie” game engines I like, maybe alongside jMonkeyEngine (since you typically don’t see that many Java game engines either).
