Well, in Naughty Dog's case, the whole game is written in their Lisp
version, so they are indeed "scripting" in the same language the engine
is written in.

I don't know how much scripting their designers do, but I think their
programmers do a large part of it.

Syntax aside, Lisp is really ideal as a "scripting" language as it is
trivial to extend, can be changed on-the-fly at run time, is a higher-
level language, allows code to be treated as data, etc. On top of this,
compiled Lisp is just about as efficient as C/C++, see:

In summary, because Lisp rules! ;)


The drawback is, I'd think, that the number of programmers proficient
in Lisp is somewhat smaller than the number of C-savvy programmers.
