Any media on our site, unless clearly
specified, can be used both in non-commercial or commercial games. The media we host is there by permission of each author and they specify what usage is available. If it is non-commercial (such as Cosmic's pinball machines or Star Trek kit), it is clearly is marked as
non-commercial in both the description and any docmentation with the archive.
Generally, it is good form to credit the artist in your development. We have done a commercial WW2 development and any media used was credited to those artist(s). It is also good policy to email the artist(s) (if possible) to let them know you have a development about to be deployed and it contains their media.
There's no problem that can't be solved without applying a little scripting.
