Tom...don't speak of things you know nothing about. Go back to your room.
Nobody is saying that the content is ours, and trem is GPL, so it's free (as in freedom) to use the textures, there just needs to be a readme/GPL file that goes with the map. This isn't ripping off of trem, its using trem's excelent textures to create a really nice looking warehouse/industrial environment. As for it not playing well, WTF? How are you so dumb? There have been no screenshots of the actual map layout, and the screenshots posted are of unfinished areas. You can't judge it until you actually play on it silly.
