Packaging Request #2220
Simutrans is a game licensed under the Artistic License
It seems that you haven't discussed Simutrans on here. It's licensed under the Artistic License which to me looks like it's free software. I have found two license files in the latest release and only one media file could be looked at since the license says that this file is an exception.
Attaching both license files.
