The code is free software (zlib) for sure.
I'm not sure about the media files license.

Hi, Pierre!

The game builds and runs fine on my machine. However, I'm not sure
about the media licenses either. The ".cfg" files in the media
directory look like scripts that the engine runs and seem to be
unlicensed, kind of like the ones from Cube 2: Sauerbraten [0].
For what it's worth, Sauerbraten is currently categorized as non-free
in Debian [1] on account of some of its media files.

Indeed.

The question is: does Tesseract reuse any of the media from Sauerbraten?

It doesn't seem like it, though I did come across some useful licensing
info for some of Tesseract's assets:

* media/sky/0ptikz/info.txt: Non-commerical clause
* media/model/mapmodel/dcp/blade_x/Readme.txt: "Cube-only, let me know
otherwise" license
* media/model/mapmodel/nobiax/info.txt: No license, but suspected CC0
1.0 (evidence: https://github.com/red-eclipse/nobiax)
* media/sound/mapsound/soundtransit/info.txt: CC-BY 2.0 according to 
http://web.archive.org/web/20160421054815/http://archive.turbulence.org/soundtransit/search/
* media/sound/mapsound/freesound.org/info.txt:
** alaskarobotics_ambient-spacecraft-hum.ogg: CC0 1.0 (
https://freesound.org/people/AlaskaRobotics/sounds/221570/)
** cascading-water.ogg: CC0 1.0 (
https://freesound.org/people/KingBowser/sounds/253623/)
** cool_compressor_1.ogg: ?
** floresent-light_1.ogg: possibly CC0 1.0? (

** rain.ogg: ?
* media/sound/game/uphys/info.txt: CC-BY-NC 4.0
* media/sound/game/soundsnap/info.txt: Non-commercial clause (

* media/texture/philipk2/info.txt: "Do-whatever" license
* media/texture/thesilentnight/info.txt: "Do-whatever-with-attribution" 
license

Also, it turns out that according to "src/readme_tesseract.txt", the
".cfg" files in the "data" directory are covered by the same license as
the code in "src".

So, this means that it's non-free?

Are "non commercial" licenses still free licenses?

Cheers!

I'm pretty sure no, even for non-code. But I'd love to hear from someone
else who's more sure than I am.

Hi,

<https://www.gnu.org/philosophy/free-sw.html>

Here it says it has to be allowed for commercial use otherwise its not 
Free Software.

Regards,
Marinus

"non-commercial" and "free license" are not related.

Well, it is hard to predict what the FSF would conclude for a such
license.  Because the terms are not really clear.  On one hand, you
can "transit the sounds as long as they are included with other
materials" and on the other hand you cannot "transmit the sounds 'as
they are' in any context".

b. To copy and transmit the sounds and available content in various
mediums or formats as long as the sounds and available content are
included in another work or with other materials;
i. Resell, rent, sublicense, transmit, and/or distribute or
re-distribute the sounds 'as they are' in any context,

Thank you.

Alternatively, we can distribute the engine without the media files,
call it `tesseract-engine' and move it to game-development.scm.
Thoughts?

FWIW, I think this is a fine idea.
