Above the booth.
People waiting in a line. That's not all of them, even. The rest are to the left, around back behind the platform, waiting where they sadly can't even see the action.
Outside of the viewing area.
The rest of the people waiting to play Bloodborne (and other PS4 titles)
Estimated wait times per game. You can see that Bloodborne (along with FFT0, DriveClub, Until Dawn, Destiny, and The Order: 1886) has already given all its tickets out, as of about 1:30pm. The show closes at 5:00pm.
