I found two MCN that are really good but there are pros and cons to both however one does offer 75/25 revshare and no lock in. The other offers 90/10 revshare plus no lock in only con is that your channel has to be completely about gaming. This channel is but still though hard to choose. Also the 75/25 network offers your videos protection from copyright and the other I havent read anything on there website that it does but it offers help with SEO.
