Yep, I think making it work in GuixSD is enough :)
Other distros have their own package.

I tried adding a gnu/services/games.scm and mimicking what the other

I would appreciate any help.

Yes, some of these games maintain and query a system-wide top scores 
list so users can try to beat each other's top scores.

This is exactly how this package does it - it installs initial, empty 
score files and chgrp's them to 'users'.
