Leipzig GC Sets New Attendance Record While the food was certainly better than E3's, there's one other thing about Leipzig that trumps LA's resident trade show: it's open to the public. And the public, they come in droves . Indeed, this year's Games Convention set a new record for attendance, 203,000 people passing through the Leipziger Messe's doors over the course of the show. That's a lot of people. More than TGS , even.
