In case anyone might have wondered why the #Galactic-Milieu uses free open-source components, including such "art assets" as it might utilise...
...Consider how much of your earnings-as-a-player you would like to spend on "art assets" and coding and suchlike.
You are of course free to donate handsomely to the underlying free open-source projects if there are art-assets or code functionalities you would like to see or hear, of course!
But meanwhile, in the interest of maximising the earnings that can be made available to the actual players, we have chosen to "scrimp and save" on such things... Players Come First! :)
