When I look at your channel, I see a gaming channel. The thumbnails look exactly how they should look to be a gaming one. They are nicely organized, there are popular games on there, the channel trailer starts out with game footage of moving around a 3D environment with a nonchalant macro-targeted voiceover that starts immediately... I know exactly what I'm going to get when I click on any of the videos. And I'm not saying that's bad. You have the formula down and for people who like watching gaming channels, there is no reason they won't like yours.
