Minecraft good for my channel?

Minecraft isn't good for any channel except for the already established ones anymore.

There's no way for a newcomer to break into the Minecraft YouTuber community, everyone has found the YouTubers they like and are sticking with them (those YouTubers almost always have 100,000 subscribers or more). Any new people who do come along wanting to watch MC videos will search for it and just find the most famous people like CaptainSparklez, Yogscast or Antvenom.

I can tell by the comments and likes on that video that you're not a bad video creator, you just need to find a game that isn't overdone. Personally, I suggest Starbound, I have yet to find a decent, long-running Starbound let's play.
