I looked at your channel for a bit and noticed you mainly play multiplayer games and they are different games, personally I like that, but depending on your subscribers and their taste in games and content you either want to switch something up or keep going like your going for growth. I am no expert at this, I am just trying to give a legitimate opinion. You can be diverse and satisfy your subscribers that way or you can try to make videos about 1 game or maybe 2 to maybe catch a bigger audience. Your commentary is good and the gameplay is also good, and I saw you do father, son gameplay as well which I think is sweet. If you would want to catch my eye or others like me, you would make videos about more story driven games like for example Middle-earth, Fallout, The Witcher, and add your own commentary over the gameplay. That would be my cup of tea. Ok, to sum it up, you need to do science on this, if your aim is to make it big with youtube you have to think of something unique that would be interesting for people like myself to watch. There are so many channels out there like yours so it would be very hard to blow up, unless you have a golden voice or you are an e-sports professional. However if you do not want to make money with youtube and you're doing it to maybe build a community or for your own enjoyment, go ahead. By the way, if you haven't played Middle-earth and you want to after my post, then it is pretty bloody and you shouldn't play it with your son. Hope that helps, maybe even a little :). Cheers.
