You can find it on the event map
here. Click on 15 (Main Stage).
But the long and short of it is it's a Jeopardy-style game show with two groups of two. They'll be answering gaming trivia questions for prizes and stuff.
I'm pretty open to contestants, but the questions aren't super difficult, so I'd hate for some Uber-gaming person to come in and run the table.
Also, If you can't go to MGC, but still wanna check it out, I'll be streaming throughout the weekend here:

In addition to streaming from the show floor, and the Game Show, I'll be setting up a laptop at the after party on Saturday night so people can chat and whatnot.
