Huh, when I went there for the Phantom Hourglass lunch, everything seemed well organized. Nobody had to play the game, participate in the tournament, or get a photo with Link to buy the game - just stand in line.
I think they must have been overwhelmed by the number of people that showed up for the event and panicked. All those "scavenger hunt" activities were just ways to make sure the sales counters didn't get mobbed by people.
