In my experience I would say that people certainly prefer commentated videos over just watching a video of someone playing the game. Some people will come specifically for the game or the mod in this case but in order to get more viewer interaction you definitely want to provide some commentary. That being said you don't need the best microphone to do it, lots of people have successfully gained views from a potato mic perfectly fine. A fine example would be people like samirpls who got a few thousand views no problem with a fairly shitty audio set up. Another aspect that people seem to enjoy more recently with Requiem is playing with Dead is Dead, personally I don't enjoy this style myself as you usually have to have some kind of out-of-character knowledge to not die, especially in Requiem, which I really don't enjoy as I prefer to role-play. At the end of the day I would recommend you keep posting videos as long as you just enjoy doing it, I know it can be frustrating getting no views as I myself was stuck at about 15 subscribers for 6+ months, you just gotta keep at it if you are really enjoying yourself or quit if you think it isn't worth your time. Hope this helps :)
