In the end it would be even plagiarism when you don't use any original assets. The layout of a level, the shape of a character or the story/plot are copyrighted too. And don't ever think of putting a glowing lightstick in your game by calling it "lightsaber". You're not allowed to use any kind of names, including Jedi, Wookie, Mace Windu, or anything else. And not making money out of it is no argument, it's still forbidden and you can get sued for it. It's just that Disney probably won't care if you don't make money out of it, as long as your game/movie/whatever is not getting too popular. If it does and they see your "product" as a rival they might sue you anyway (for example releasing a free, fanmade SW-MMORPG when an official SW-MMORPG get's released). You always have to remember that big companys have shittons of lawyers whose job it is to sue all day long everyone who broke copyright-laws. Saying this, I don't think it's likely that these people will get problems with Disney. But some of you people here seem a bit naive :unsure:
