This is true, but it is not useful as code and art (sic) have different
licencing requirements and are simple enough to tell apart.

Which is likely when the work can usefully be re-used.

Sure. So BY-SA the text and GPL the code. If this is a problem as
currently written, refactor the code to remove this problem.

And so we cannot write BY-SA novels in GPL word processors, or in LaTeX.
Which is a problem... :-)

As a Lisp hacker myself I can hardly disagree. :-) But we are not
discussing data and code, we are discussing executable functionality and

"Compatibility" as used by the GPL means that a combined work can be
covered by the GPL. But the combined work is the program, not
necessarily its game assets as per the GPL FAQ.
Proper structuring and licencing of games may be more effective than GPL
