Nailed it. A couple years back my channel and it's following peaked because I focused so much on the competitive FGC and GETTING THE GUUDEST at a specific game, like Marvel. After dropping that, I started to cover games outside the 'Only Capcom Variety', and actually began to enjoy playing fighting games a lot more. Was perfect because KI got announced and there was a lot of stuff I wanted to explain why it was so good back in the day. Growth got a lot better, and I was happier with the little time I had to play the games.
Long story short, I focused a lot of my content more around entertainment and less about being on hardcore tutorials and FGC news(there's already thousands of videos people trying to prove hot 1337 they are), while not completely excluding the later. Now I only make vids about games I'm interested in, and convey to an audience that didn't even exist a year ago, why it's awesome and why they should check it out. Also, Benny.
