How would you feel if you worked on a big play set for your kids for a couple of days . Then you go outside and it ' s no where to be seen , instead you see it on your neighbors ' curb with a sign saying free to a good home . If you CREATE something , from scratch , it is 100 % yours to do with as you wish . Doesn ' t matter if it ' s all code or a fucking swingset . NO ONE has the right to take what ' s yours and give it away . Unless the creator says it ' s okay , which in this case we don ' t know if it is . Wyrmstooth has a copyright just like how Skyrim does , and technically , the maker of the mod could cause legal issues , it just wouldn ' t be worth it . So no , it ' s not different just because it ' s free or not called DLC .
