State of Decay series
Details and Conditions
Undead Labs does not have an official policy statement but it would presumably be the same as their parent company, Xbox Game Studios. From my experience, you can still get copyright claims based on the music used in the games. If you're disabling the music in the game, you should be fine. Otherwise, you probably won't be able to monetize your videos.
What it Means
Videos and streams ARE allowed
You SHOULD be able to monetize on YouTube and Twitch with ads and subscriptions
You MIGHT NOT be able to sell or charge for access to your content (this would include Twitch "subscriber only" streams)
Any licensed IP or music not owned by the publisher are not covered by this policy
