I thought it was strange and sad. I did notice that not many people were watching though. Still surprised as online gaming has a big future and they invested a bunch of money capturing expensive streamers.
I preferred Beam! I thought it sounded much more interesting. With Mixer I didn't really know how to search for games - don't make me brows or I will just leave.
Facebook Gaming? Nah, I don't even use facebook anymore. It's just so sad and creepy.
