Need Help with Uploading Variety of Games to my Channel

[jbird]

I started my YouTube channel a couple months ago, and I have about 20 videos. The problem is all of my videos so far have based on one game (Call of Duty Zombies) and whenever I post anything else, such as my latest Battlefield 3 video, it gets no views and it is as if I were starting a brand new channel.
Is there any way I could help increase the views on my other videos? I don't want to be stuck with having to upload only one game because it's the only thing my subscribers are watching from me.
Help would be appreciated, thanks!

Saturated markets my friend... Call of Duty videos are my least popular uploads because EVERYONE does them. It'll be very rare that people stumble upon a small channels COD videos.
