Thanks for the explanation.

I am convinced that eventually AAA game engines can be
made in a GC enabled language like D, they just need to
be coded in a different way, more GC-friendly.

I tend to disagree. I see it trending in the opposite direction.

Tight pooling of resources and updating in finer grained (probably threaded) tight loops across neatly (cache friendly) packed bundles of like objects. That's where engines are going.

Engines are becoming more and more memory-layout aware, not less... GC is the opposite of rigid memory layout.

It's great for high level sugar that glues the whole thing together, but the engine is heading the opposite way; everything works more like a video card, small repetitive streamed jobs, with memory carefully managed.
