While I don't get to stream as much as I'd like to, I do enjoy streaming a game or two. While I'm not the most popular streamer out there, I'll do this for myself and if people come in and we get to talking, it's that much better. Not going to lie, I did stream on Twitch a lot in the past, then made the move to Mixer and had a decent following. Sadly, I wasn't able to recreate that magic on Twitch when I moved back. And that's ok - I play games to unwind and have fun.
As for streaming opportunities, I was blessed by Ubisoft who allowed me to stream Watch Dogs Legion ahead of the official release date. And you're looking for streamers for an upcoming game event, and you're considering smaller streamers/content creators, I'd love to chat with you.
