I went to the bottom of pinside's top list and found the 16 lowest ranked mainstream games (no boutique or special order games). This is round two of this poll, with 8 games remaining. Round one can be found here: https://pinside.com/pinball/forum/topic/worst-pinball-machine-in-the-last-decade
There were no surprises in the first round as all of the higher ranked games beat out the lower ranked games. The closest race was Full Throttle beating out Munsters as the worst of the two by a vote of 105 to 132. Munsters fans can rest at ease!
Remember that you are voting for the worst games, each one that sucks more than the other that it's paired against.
