Do you ever watch people game on Twitch?

Nope, I'd rather play. Currently on an ESO kick :)

Not only do I watch, I am a streamer on the platform (sippycupgames)

I like seeing gameplay videos just to see how a game really is, trailers are not a realistic depiction of actual gameplay in most cases. That being said, I do occasionally watch a youtube video or catch a livestream. Generally though, some of the peeps I followed on youtube have migrated to twitch and are now charging subscription. I have caught a few twitch vid's, usually from friends who have shared their latest "super kill, so proud, yay me" moment. As for paying to watch other twitch videos, no thanks. My paycheck can go to better things other than watching somebody else play a video game I want to play.
