The biggest drawback for me atm is the stuttering you make and the time it takes for you to explain simple things.
Other than that keep up the good work. I tried YT too, but gave up as I am too much of a lazy person, and my PC is currently a lil' outdated.
Also, you might want to go for starbound beta. It's on the trend atm, and it's a sandbox, meaning your content will be unique.
Basically sci-fi Terraria. (platform minecraft, if you don't know that one)
