Advice on starting my own twitch channel.

[SpookyZalost]

So now that I have the time and resources I'm finally getting setup to start streaming twitch channel. I've got a webcam, I've got a decent gaming PC, I've got a greenscreen and lighting setup.
So my question is there. What games are a good place to start for building viewership? What sorts of things do you think would do better than others? Honestly I'd love any advice I can get.
