Game audio is way too loud IMO. There are times when I'm not able to hear what you're saying

Also, 29 mins might be way too long for a video like this. It may be a good idea to set a 15 minute maximum length for yourself, and then be really picky about what to leave in the video. This is a good way of upping the entertainment value of the video quite a bit

It would also make sense to lose that intro. Might just be me, but intro's aren't really worth much if they don't serve a specific purpose. Your channel should be able to brand itself through artwork and thumbnails, not some intro that's going to annoy people rather than draw them in.
