Took a sec to actually think about this before speaking against this sentiment of litigiousness that keeps popping up. Now i still feel that's not the way to go, but i did look up a legal definition of false advertising

Depending on how you interpret those 5 criteria, i guess "sue now, force better business behavior" group might actually have a leg to stand on if Skyrim DLC doesn't happen.
If you knew how much large companies go out of there way to make sure they're covered in legal terms, you would think they're totally paranoid. It's crazy, like they're just waiting for someone to sue them. They have massive legal teams that are so cut throat they would counter-sue for trouble, possible slander and damages and end up taking you for all your worth. Whether the particular company your suing agrees to it or not, their legal team would make sure the plaintiff would never be financially stable again.
I'm not an attorney and know very little about law, but I would highly suggest making sure you have one hell of a case before serving them with a citation, lilace95. I don't know if interpretations under the pretense of false advertising would hold up. Who knows, you might hit one out of the park. Lol
