Nobody cares what you play so long as youre entertaining and generally not irritating (that is a general thing, im not speaking at anyone is specific)
Not to mention, dont even consider something like minecraft at this point. Any idea you have for it, has probably been done by several thousand other people. Its overdone and has been since '12
Youtube and other view based services such as Twitch rely second to entertainment on commitment.
Make a schedule and stick to it, if you are consistent with your content and uploads you will eventually build an audience. Do note people tend to not watch gameplay that looks bad, or is choppy.
Take a youtuber by the name of kosdff for example, he focuses on funny videos with friends trolling and gooning in games and his sense of humor couples well with his gameplay, and thus gets views. He is absolute garbage in games such as GO, but thats not his goal. (not an advert)
