Before you make a decision of what to record, look it up and see what kind of competition and how much competition you're going to go up against. Odds are with many popular games (GTA, CoD, Minecraft, The Last of Us) that you'll never get many views because you'll be put up against titanic channels.
In the case of GTA, you're going against Vanoss and his crew. You'll never get on the first page. You'll come close if you get a video on a new expansion really quickly. But that's a strong maybe and you still won't get on the first page.
In the case of Minecraft, you're going against many titans where their entire brand is based around it.
In the case of CoD, there aren't as many titan channels as Minecraft, but there are thousands of channels where it is all they do.
You get the memo. You won't get far with throwing things that won't stick.
