I'm back from the Micromania Game Show 2006 here in Paris. It was very crowded. They distributed some kind of tickets to enter in a booth so that you could play.
For the PS3 they distributed 50 tickets for one person every 30 minutes, and you could only play for 5 minutes. But As I was lucky to have a press badge and my teammates managed to bargain so that we could spent all the time we could to play. I played about 3 hours.
