We currently do not have any special licenses, so if nobody is allowed to upload a game, you can assume that you are not either. Please make sure that you do not violate any copyright regulations when you upload any Gameplay footage to avoid a copyright strike.
We cannot give you advice on what you can and cannot upload because we do not have written permission or a licensing agreement with any gaming providers.
If you see a channel that is uploading and monetizing specific content it does not necessarily mean that everyone else is permitted to do the same. That channel/content producer may have acquired special licenses from the content creator so please do not assume that the content is copyright free.
You can learn more about global game release dates by checking online as we are not able to give definite answers on specific games and dates due to variation from publisher to publisher.
