I agree about the sound, I am hearing the game more than you, if you can lower the audio for the gameplay and have your voice so it is just a little louder that would be better without messing up the overall audio quality at the same time. I think on your latest Amnesia video that you keep the talking going very well, I watched an earlier video first and that is a big improvement. I think it could do your channel some good if you do some specific tutorials like How to do such and such in such and such a game, a proper example of this would be Getting a MOAB in Modern Warfare 3 on Lockdown, things like that I think are more interesting than lets play videos because it I believe it makes the video more worthwhile watching to the viewer as they get to see your technique and perhaps learn something from you and that is when people will remember you more. Maybe ask some questions to your viewers to provoke a response, maybe gaming related or if you cant think of anything then anything they could answer, even things like I would like to know what games you play yourself or what would you like to see me play will help get some comments for you. Other than those things I cant think of much more, just keep promoting yourself on external sites like here, Facebook and Twitter and improving as you go.
