Scared me with that first paragraph! xD
I think it's mostly logical stuff. Focusing on one game at a time, improving the thumbnails and video edit, throw some posts in the blog to add variety ("brains"), it's all good.
You should poll your followers as to what game you should do next. Give us some options to choose from ;)
As for not upvoting comments, don't worry about that. In fact, most blogs where I leave a comment (a real one, not a "nice, dear" or "great post") never even bothered to reply, let alone upvote. Just do your thing :)
I know that no one upvotes them and I also know that is the reason why few of my followers even sticked with me. Thats why it is kind of sad that I can't realy do it atm.
Same here. I have a handful of good buddies (including you) but the rest is either spam or non-existent. If you were a whale (I mean, a WHALE), you would get tons of followers. Steemit is based on interests more than an actual community, really.
And I commend you for delegating some of your power to a fellow gamer (Piccollo, I guess?). That already makes you more honorable than 95% of the users in here.
