I think you need to put yourself out there more in terms out "LOOK AT ME!" thumbnails and Titles.
Take for example when somebody does a blog. Normally, I'd never click a video of someone talking, but if it were between clicking the one with the well done thumbnail that looks professional (as far as youtube standards go) vs just an image of a guy, I'd click the first one.
Your content seems too cut and dry. Don't take that the wrong way, either. What I mean is that you need to add some excitement, maybe not to the level of PewDiePie, screaming so loud it makes you want to turn it off, but not so much just watching you play the game. Anyone can play the games you are playing, but it's YOUR job to make them want to watch you and say "Damn, this guy is hilarious!" or "I love his stories and the way he words things! Plus, he's got great advice!". Don't be afraid to be yourself, right from the get-go show people who you are. And if it takes a bit of fabricating in terms of making yourself seem more excited than you are, who cares? Youtube is entertainment. Even if you present a a tutorial video that teaches you something, it still needs to have some aspect of entertainment and not simply the HOW-TO. Now, that's not your fault, but it's pretty much a way of roping in the 10 second attention span of most people and getting them to stay.
To expand on that- The first 30 seconds of your video should be exciting, those are the few seconds that count the most and determine whether or not people will want to watch the rest.
Another good example..... Say I wanted to look for a video of a loud Ferrari wreaking havoc on the streets and terrifying innocent little smart cars.
Would I put - Ferrari F430 on the streets of LA with Tubi Exhaust.
No, you'd put - LOUD FERRARI! --- LOUDEST FERRARI EVER! --- AMAZING SOUND FROM AN F430!
My point is this - You don't need to make your video sound like the best thing ever, but make it something that people would want to click on. A LOT of the times, simple is better. And chances are, if you have a video that is REALLY good (Which it should be if you work at it!), then you will feel comfortable with putting titles like that and you won't feel as if it's false advertising. Trust me man, it PRESSURES you into making great content!
Thumbnails, I'm still kinda new at. All I can say is don't just have crappy text with bright colors, it can be a mix of both! A vibrant image that illustrates what is in your video. Really though, you should do thumbnails, like I mentioned in the example above with the people talking.
Tags, yeah, they are a pain in the a** but in the end they will probably help you out. And maybe not right away, but what if your video gets 300K views, and you simply typed in the tags "Ps4, launch, leak". You see, even if people type in something random and your slender video comes up, who's to say they won't click it?
I have so much more to say but most of it is sort of "iffy", considering I am still learning too.
Good luck on the channel man.
