If Microsoft hadn't killed XNA (what MonoGame is based on) a decade ago, they could be packaging it with Copilot right now as the ideal code-first AI-assisted game engine. Easy to use, easy to test, no visual editor where AI will struggle like with Unity/Unreal/Godot.

I am automating Unity with headless method invocation of agent authored editor scripts. I don't think "struggle" is the word I'd use to describe how GPT5.4 is currently performing.

I can tell the agent things like "iterate over all scenes. Wrap lightmap baking in a 5 minute timeout. Identify all scenes that exceed baking time. Inspect the scene objects and identify static geometry with poorly configured light map scale relative to their world space extents."

Microsoft's head died long time ago. Corpo parasite took control of the body completely.

If they hadn't killed it, it would have a visual editor by now. Or worse, dominated by Maya integrations.

For Lazarus (an IDE with visual components similar to Delphi) I switched to code-first components and did away with the form files. You can probably do this with all of these frameworks.
