Details and Conditions
I was not able to find any information regarding DONTNOD's policy on YouTube monetization, nor have I attempted to contact the developer. You may have to refer to the publishers for the respective game that DONTNOD has developed that you are looking into (ie, Square Enix for Life Is Strange, Xbox Game Studios for Tell Me Why, etc).
From my experience, though, almost every video I have uploaded using their most popular game, Life is Strange, has received copyright claims from music featured in that game. Unless you're trying to get permission to monetize a video featuring one of their other games that does not contain licensed music, I wouldn't bother contacting the developer for Life is Strange as they would not have control over the licensed music anyway, and the IP itself belongs to its publisher, Square Enix.
What it Means
More research is required
Any licensed IP or music not owned by the publisher are not covered by this policy
