I enjoyed both channel ideas and see no reason not to mix them. vlog style is a nice change of scenery and the gaming review was well done but I'd rather read it as it was a little drawn out to listen to and more In-Game footage was needed.
it was kind of like getting a lecture on the game rather then hey here is a cool game to play because of this,this, and this.
maybe do game recommendation rather then reviews or game commentaries as both I feel are over done everywhere else.
Overall I would like to see both options explored for your new content.
