Want to make money on Twitch?

I want to start gaming on twitch and I wanted some advice
What games should I play
What are good cheap mics
Is obs good for recording
How do I make money from this
How do I get people to watch my videos
What is the best recording software
How much money will I probably make
What's a good facecam
I'm not a noob but these are questions I wanted to know the answer to

Thanks guys 1. League of Legends (If your super good at it), Minecraft (Huge Community), Hearthstone (have to be good),
COD (only competitive though), GTA 5, Destiny, FIFA, DayZ/H1Z1, just play whatever seems to be popular.
2. Blue Snowball, don't recommend going lower than that
3. Yes OBS is good, turn up bitrate for better quality
4. You need to set up a donation page (Twitch Alert), you can make money from ADs but only once your big.
5. Always talk to viewers (they will return), stream daily for a few hours, be funny, and most important is to go on Twitter or reddie and talk to other people and get yourself out there.
6. OBS is fine for Twitch Streaming and YouTube recording, Dxtory is popular but only for recording not streaming.
7. You rely on donations until you get big (1000+ viewers on Twitch), somedays you could go all day and not get a penny. Some days you'll get lucky and someone will donate $20. You just never know it depends on how much you stream.
8. Cheap: Logitech C720, Good: Microsoft LifeCam, Best: Logitech C920
