On what concerns video games, all major engines do use GC on gameplay code, including variations of C++ GCs.

emphasis on gameplay code. And even there, if you target 60fps (sure a minority of developers), then GC is a liability at best.

But that is exactly the point. One should not constrain productivity just based on hypothetical goals, web scale and such similar arguments.

Doing the next Fortnite, Crysis or ground breaking AR/VR/Ray Tracing? Sure, every ms/byte counts.

Doing a typical Flash like casual game, game prototypes at Ludum Dare, participating at IGF? Having a GC around isn't the biggest concern.

But for those cases, what would move you to use D instead of an entirely memory-safe language like Python or Lua?

To justify using D for games, you'd need to find a use-case where speed (e.g. targeting 60fps) is high-priority enough to be writing a lot of low-level code; and yet, where "having a CG around" still won't cause problems. Can you think of one?

Yes, because it compiles to native code and has relatively fast compile times.

Some AAA studios do use D instead of a C++ based script language exactly for that.

Only one studio, no more. And I hear there are some questions about this decision...
