^ The funny thing is besides Jaxel and Fahros, I'm probably the biggest youtube user / uploader on this site... xDNot sure what percent of this is a joke, but if it really was that simple a lot more people would be doing it. The chances of your channel actually going big are near-zero, which is why most of the people who have these channels also have "real" jobs. It's just that the big channels have grown so large that they can sustain themselves (PewDiePie, etc) so the creators just take the obvious course of action.
That being said, I know what's easy game videos to make, and what's quality.... Quality would be you going 100-0 in Call of Duty, it's tough to do. Quality would be you having 5 people rage quit on you for spamming, it's entertaining! Quality would be uploading video game tournaments.
Easy money on Youtube is buying a game day one like GTA5, plugging in your PVR, playing it... mass uploading it to Youtube and expecting to get paid ridiculously well for it. Not like Youtube cares, Youtube will always be Youtube and people will still upload mass videos to it! =3
^ Archfiend sums it up pretty well if you watch his video.
