Why would you not upload converted mods, some people who made mods may no longer bother with the game so they would never get converted and uploaded unless some one else does it. Surely that’s the spirit of creating a game open for modding. So people share their developments/conversions.
Copyright is a different story and beast all in its own. Giants, so far is the only one I know that can sue for using mods. Unless someone patents the mod and pays the rediculous 2000 fee per mod. Those boys probably work for giants. So enough hate on all these mod sites and more developments/conversions
