Ok again as I said the reason we did the prizes the way we did them was so the same people could not win the prizes all the time, Xavierking your still new to the club and don’t realize what it has been like at past LANs, the same person walks away with almost all the prizes, with the way we did it anyone had a chance to win a prize, much better that way, instead of the same 2-4 people getting all the goodies.
Also the method you named is called Dirty Santa and your right it would not work well at all at a LAN event.
