Not every video on the channel is a game. These are from gaming conventions: panels, booths, games on the show floor and a lot of cosplay. Each video has its own page with the video embedded, grouped below by event.
Minecon 2013
Four videos from Minecon 2013: the Mindcrack party the night before, both days of the show, and the stage before the Mindcrack panel.
PAX Prime 2015
Two videos with Team B.S.: a round of Keep Talking and Nobody Explodes, and a look around the show.
