Not embeddable, from the start

Is this a viable suggestion, though? Correct me if I'm wrong but I imagine that developing the entirety of your video game in Forth for anything but desktop operating systems would mean writing your own tooling and API bindings, if not your own Forth compiler.

It is pushing the the machine model to where it is most appropriate, on the iron. No different from choosing Javascript because it is cross platform, just someone has already done lots of the base work.

Forth has strengths and weaknesses, lack of wide use on modern platforms is definitely a weakness. There is still plenty of Win waiting in there.
