I'm not a competitive pinball guy. But I do open my home for a travelling charity pinball tournament once or twice a year--100% of the proceeds are donated to the charity. No payouts at the end of the night. It seems that the promise of IFPA points paired with a good selection of games is a good enough draw to get people to play without a prize pool. Maybe it is more of a PITA to collect an extra buck from people who walk through the door...because it wouldn't be fair to dig the dollar out of the entrance fee, thus taking money out of the charity's hands.
Thank god this isn't my problem...the tournament organizer has to deal with all the gripes and groans and headaches of this new fee.
