this pisses me off so much. it's unbearable. dirtbags. all of them
Understand this (yes, I know I'm coming back in):
Without copyright, there would be no "non-commercial use" items available. Copyright is what gives you the power to limit how your work is used. Without it, anyone could take your "free game", and either sell it (probably bundled with a bunch of other "free" games), or rip the assets out to use in their games. If you want people to respect the work that you have done in your creations - whether games, scripts, sprites, tilesets, music, whatever, then have the same courtesy and respect the rights of other creators. It is possible to license most commercially released stuff, and they've tried to streamline the process for smaller ventures to do so (Harry Fox being one example)
Whether or not money is made makes absolutely no difference - all that matters is was the material copied? If it was, it's infringing, and you are liable for whatever damages you either settle for or the court decides. Whether or not you charge for your game has no bearing on this. Infringement is infringement - whoever you've copied from isn't getting the license fees they should be.
If you use a song in a free game that one hundred people download, that is one hundred license fees the RIAA did not collect - and should have. So there are ALWAYS economic and financial damages in a copyright case.
Here's one last clue for those still not clear on this - the majority of "filesharers" being hit with DMCA takedowns, 'strikes' from their ISP's, or being brought up in civil suits didn't charge a dime for the stuff they were distributing.
I wonder how many of you would as cool with me just taking Celiana's or Lunarea's work from this site and using it in my commercial game without licensing it from them first as you seem to be with ripping material from other sources.
