The only system launch I ever attended was the Gamecube's, back in 2001. Since the Wal-Mart I was at was in a small town, there weren't too many people in line, and at about 10 o clock, they actually assigned us all numbers and just told us to come back around midnight.
But I can't see myself doing it again. I mean, I honestly don't mind waiting a few months to get a system anymore. And I certainly can't see myself getting into a fight over being one of the first.
Any word on how it went at your store, Ulticron?
