Alternatively, you can point out how many GPL'd games are using CC
BY-SA music, while the licenses are incompatible, and the music was
composed independently of the project:
and even GPL + weird non-free license (though in this case from the same project):
There are countless other examples in the archive.
Of course the combination BY-SA+BY-NC cannot be used in a commercial
context, but as you point out it should be possible to make an
alternative BY-SA-only with music replacements (or no music).
SunRider is describing themselves as "a 100% free game which is open
source, DRM-free, and free to modify and use for all personal and
non-commercial purposes" (http://sunrider-vn.com/main/donate/) so even
if their repo says "NC" (https://github.com/vaendryl/Sunrider) I
believe they are good-faith'd.
