Should i do the commentaries?

Go for it. You never know what happens, and don't listen to haters, they just be hatin. Ahaha, but seriously if you enjoy playing the game, and talking then do it for fun, but a tip is don't just talk about whats going on in the game and what you're doing because thats kind of obvious, but talk about somethings interesting such as maybe something you did, or other topics that would interest your viewers.
