I have just a couple of things.
1.) Audio is too cluttered, either lower the volume of the music and let the viewers listen to the commentary, or strip the video game audio completely and let music and titles do the talking for you.
2.) I agree that you should lose your intro for just the trailer.
3.) Keep "subscribe now" on the screen longer, that way it sticks in your viewers' minds.
Other than that I think it's pretty good.
