Wrong game
From Glitches
Apparently even people in the bsesnuis have no idea what they're talking about. You do not need any disclaimer on a text walkthrough copyright, and you can sell them to whomever you please. It is your creative work, not the work of the game company. Sheesh. If I give you the answers to the questions in a textbook it isn't copying anything from the text (at least nothing that is protected by copyright) so (a) I don't need permission, and (b) I can sell them to anyone for any price I choose.On the other hand, if you MARKET something that appears to have the same trademark as another company in the same bsesnuis area, it could be a trademark infringement , but not copyright.If you take a video of a game and add stuff (for a walk-through), you would need a license to distribute the derivative work you have created using someone else's creative game video. Without a license it would be a federal crime to sell one.
