I've ran a gaming channel, and I've also ran a vlogging channel. Here's what I've noticed.
Gaming channels, in my opinion are a lot hard to start than vlogging channels. You search for any game, you're going to get results from people like PewDiePie, Yogscast, Cry, and so on. These are have tons of views, which are then followed by the smaller gamers. Because of this, any title you do will most like be a few pages in, if not a lot.
Well what about if I did a Let's Play of a game that just came out? I tried this as well to see the results. I pre ordered the game, and downloaded it as soon as it was out. The game was 'The Night of the Rabbit', and it got quite a bit of coverage. I had a video up within 30 minutes of it's release. Now, this video to this day, has 123 views. I was in direct contact with the developers, advertised on their Steam page for the game, and thought I was going to do pretty well. Searching for the game now, I don't even show up on the first page. Why is this? Well, even though I was one of the first, I was quickly flushed out by bigger channels, their videos getting more views and quickly pushing my videos further down the searches.
As well, as a game series goes on, it slowly diminishes in views. This could be because A) The commentary sucked B) The commentator is a terrible gamer to the viewers standards, or C) a bigger funnier YouTuber did it.
For my gaming channel, my average amount of views is between 2 and 11 for each video.
I got a little offtopic there, but lets get back to the vlogging.
Vlogging is unique in it's own, because it has more personality than gaming. You have more wiggle room to express yourself, so a lot of your success will depend on your humor and how comedic or entertaining you can be about it. With my gaming channel, I represented myself on forums as a gamer. I even put a fair amount of advertising in through AdSense. I completely ignored my vlogging channel in terms of promotion, because I was more focused on my gaming channel. But something interesting happened. I started gaining more views on my vlogging channel than my gaming channel. No advertising, no promotion, yet my vlogging channel was quickly beginning to grow. My titles weren't deceitful or a lie about the topic, and heck, the majority of them I wouldn't think are being searched for either.
For my vlogging channel, my average amount of views is between 10 and 25 for each video.
With all that being said, I think mainly what you need is a little more promotion, and a little more patience. Collaborations, being active on forums here, being active on social networks and gaining a following. Very few become famous over night, heck I even know some YouTubers that are three years in the game and are just hitting 10k, and I know some that are under a year in the game and sitting at a nice 17k. It all depends on promotion, with a little bit of luck and patience.
