To any aspiring game developers out there: If you need AAA-equivalent graphics and are willing to tank the overhead, use UE5. Otherwise, homebrew everything in the language you prefer (use an LLM, make sure you understand the architecture perfectly).
Using a half-baked semi-supported game engine which you don't understand will destroy your project sooner or later. The cognitive overhead of understanding someone else's code is far, far higher than using your own. If you can't handle any of this, get a developer on board who can - you aren't equipped for this.
Eh, what's wrong with using Unity or Godot or GameMaker?
As mentioned there are plenty of engines mature and worthy to develop with, like Godot.
Advising to homebrew everything with an LLM just sounds insane to me. Cognitive overhead of what? Using well thought out and standardized libraries that have proper documentation? Creating a new engine with an LLM is only going to achieve the opposite of fully understanding your codebase.
