What do you look for in a youtube gaming channel?

Pretty much as the title says. I'm thinking about starting a youtube channel that is primarily focused on making content related to League of Legends, Counterstrike, Hearthstone, and Blade and Soul.

I would love to hear the community's thoughts on the matter and what they would like to see in a channel with a diverse game coverage (or at least thats what I am aiming for)

P.s ive got the hardware and software covered
