^Like he said, personality is what drives a channel. Try to show off your personality and your humor.Playing games that are fairly new is your best bet.
Honestly though, gaming channels are driven more by personality than by games. At least ones that earn consistent traffic.
Darkouls 2 when it comesout! cs go! and ofcourse battlefield4 !!!!!!!!!!!!On YouTube, gaming is HUGE. This is going to be simple, what can I do to differentiate myself? What kind of gaming videos does YouTube need more of? A specific game? A certain type of playing a game? More walkthroughs? What can I do that others can't or don't?
