i dont think you earn much if you dont have viewer numbers over ~1000 regulary, at least not enough to make it your only income.
also iirc fazz said a few months back that he got a couple gundred bucks from the sub money, but really not much

Those are lies because he doesn't want you to start steaming and stealing his millions, duh

3 rupees

you make pocket money, mostly.

There are plenty of people who make a living streaming games other than CS,Dota or Lol, but they do need to have a moderate amount of popularity yes.

Just look at what this guy is playing for example: http://www.twitch.tv/hutch/profile/past_broadcasts

What matters most is how entertaining you are as a streamer. A lot of which seems to come down to how much you are willing to whore yourself out and how retarded you can act, unfortunately.

or, when it comes to csgo, you actually gotta have some skills (or tits+giveaways in kittyplaysgames' case...)

Yes, and also in the most popular games the competition is much bigger in terms of number of streams, so it's much harder to stand out, make yourself known.
