Minecraft is a very popular game, dont do only minecraft beacause, people in theses days only watch popular youtubers like DanTDM, SkyDoesMinecraft, Deadlox etc.
Try to play the latest games avaliable, you'll get more views on your videos.
That is all i have to say right now. Good Luck dude i know you can be awesome youtuber. Follow your dreams.
