By that logic any Chrome extension that modifies the contents of a copyrighted web page is illegal. Holding up an automatic translation device to translate what is being said on the TV would be illegal etc. There are nuances of course, but I don't think it's a problem here. > That's why I'm also wondering how the law deals with using things you have a license for in different ways, for different purposes than originally intended. I really don't know much about law, just trying to apply my common sense here. I think the difference in this case is that there is a single customer that _uses_ the extension to modify their experience, not a large corporation using a product (game engine and content) for unlicensed purposes. I could see why Rockstar would potentially want to keep the right to license the engine for these simulation purposes in the future, in which case they'd have to block this kind of use of the game directly.
