sorry, I should have been more clear.
MGC is way larger as the show is WAY larger than PAPA. If you are only concerned about # of pins under 1 roof then Papa stores around 400 that are there year round and available at PAPA competition.
MGC will feature probably 120-150 pins, the majority of which tend to be amazing condition that local and regional collectors have spent countless hours restoring to better then new condition and moding out with all sort of cool stuff. The actual pins changes each year, but the quality and # continues to increase. However, the pins are only a small part of the total show.
As others said MGC is about the people, the vids, the board games, the cosplay, the people, the good times, the after party, the people, etc... In sheer quality/quantity of show and # of people in attendance, it is not even close in size comparison. MGC dominates and honestly is way more fun than PAPA ever could be for me. For reference, PAPA 2016 had less than 500 competitors in attendance. MGC had 4 different competitions with over 500 competitors last year and competition is only a small part of MGC. I would guess MGC had over 5000 in attendance each day last year, but I dont have any numbers.
I enjoy competitive pinball but PAPA is actually not a 'show' per say. It is a competition where you will spend the majority of your time on a bank of 10 games (you may also spend your time on the classic banks and playing some of the other games that are not even part of the event but stored in the facility). PAPA I m sure had a reason for opting to conflict with MGC, but MGC will win everytime for me. Like doug I am very bummed to not be able to hang with some of my friends at MGC but wish them luck at PAPA. PAPA is tons of fun and I dont want this to become some sort of pissing match as both shows are a great time. I really just wanted to make the point that MGC is the larger show and PAPA is the one that elected to change their date for whatever reason (I am sure they had their own good reason that they had to, but I hope in the future they will move it later/ off MGC weekend)
MGC has been in the second weekend of April since 2014 (used to be in March but was moved due to better weather in April typically)
PAPA used to be held in August, then switched to March in 2015, and then switched again to second weekend in April in 2016, and now appears stuck on that conflicting weekend.
