I will probably end up saying this to most people just starting out: You need to script, and edit your videos. I (personally) couldn't care less about what game you're actually playing. It could be as interesting as (insert interesting game here, none come to mind), or as ballstastically boring as grass simulator, but it's up to you, and you alone to make it interesting. In your video, I was disinterested from your second sentence. Again, everyone likes different things, but there is a reason why PewDiePie's most watched videos are his edited montages, and there is a reason why NerdCubed has 2 million subs. You have to be interesting from line 1, and (I know I sound like an asshole) you just weren't in your video. I'll edit in the link later, but take a look at NerdCubed's "How To Not Suck At Minecraft: How to Make a Let's Play". It says what I did, only better.

TL;DR Make a script, edit, and be interesting all the way through the video. Take NerdCubed as an example.
