Hey SMTV Nick. I did the same as you, I started as a streaming channel & got a bit of growth through a COD-BO-3 campaign I did & then started moving towards actual video content like reviews. It is really hard to make waves in the gaming community, but what I find really helps me grow is video quality & community engagement. How many subscribers do you have?
Another thing I noticed people like is when you take requests, it shows you care & are there for them.... ultimately that is what we ALL should be doing is being there for them.
