A large problem that youtube gaming has is that Non of the bigger streams that I watch like iijeriichoii, timthetatman, goldy, or syndicate as well as any of the top tier esports will likely ever go to youtube gaming. This is because of how big of a foothold twitch has on the streaming market. So if they did stream on youtube gaming there won't be the thousands of viewers and without thousands of viewers they can't stay in the business of streaming.
