Recently, Microsoft made some changes to Game Content Usage Rules. It created confusion among users related to Game titles and describe their creations. Microsoft is aware of it and they will be updating the language in the policy to provide some more examples and clarification of this clause with the revised version below:
In addition, your Items may not use the name of the Microsoft Game in their title to give the impression that Microsoft is the source of the Item, or authorized or endorsed the Item. Items that make referential use of our titles are fine, for example, “Let’s Play Forza Motorsport 5” or “Tips and Strategies for Halo 5.” Using the Game title to tag your Item on social media is fine. We also don’t object to “Red vs. Blue” or “Operation Chastity”. But we may object to “Halo: Covenant Strike,” for example, if it could be confused as something Microsoft produced or licensed, or if it could be mistaken as an official part of the Game. We just want to make sure consumers don’t get confused.
Rest assured, we have not seen rampant abuse of this and we’re not actively seeking violations on YouTube and Twitch. We love that you’re passionate about our games and we want you to create great works. This is a small way for us to protect against abuse. Sorry if there was any confusion.
