ARTWORK
The artwork on your channel looks really good. I just suggest you use a different font for the small text within the banner.
DESCRIPTION/TAGS
Your tags are really good and its great that you use a lot of them. I suggest you order your description better and get rid of the extra tags at the bottom. In your title, you put the game name and them the main title. These should be switched around.
ex: What if Michael Jordan replaced LeBron James on the Cleveland Cavaliers? - NBA 2K17 Scenarios
VIDEOS
Your intro is completely pointless/cancerous. 3D intros are probably one of the worst things you can use to make a first impression. Your mic quality is pretty good but it could be improved. The rest of it is pretty good.
SOCIAL MEDIA
You don't seem to be using your Instagram or twitter often. Those two are very helpful in promoting yourself and you should really consider using them more.
Keep working and your videos will be great
