You see, I think that its hard to jump straight into Gaming Videos, however, if you build up a solid community of followers, I believe that if you do gaming videos, your viewers will watch it because they enjoy watching you as a person, and most of the things you do is entertaining to them, and after having a quick look over your channel, I think that your views really fluctuate depending on the type and topics of your videos. You could give it a shot, make it as interesting as you can without overdoing it and then make your own judgement as to whether its a good idea or not.
Also, something I learnt recently is that tags are extremely important. You can set up some default tags and then add others at any time, and I think if you don't add vital tags, you video won't do anywhere near as well
