I've been bringing games to MGC for quite a few years, as well as helped out in the arcade hall. Games I've brought to MGC include:

2007 - The Three Stooges
2008 - The Three Stooges and Sinbad
2009 - High Speed
2010 - Jokerz and Eight Ball
2011 - The Simpsons Pinball Party and Eight Ball
2012 - Twilight Zone
2013 - The Addams Family

On average, the games get 600-800 plays during MGC. I had a switch completely flake out on TSPP and a broken plastic on TZ. Otherwise, no issues other than some burned out bulbs and the playfields getting a little dirty. I figure, if I want to continue having a pinball show in Wisconsin, I need to be willing to bring games to support it. In my years in helping with the arcade hall, I've never had anyone tell me they regretted bringing a game or that they wouldn't do it again. Hope to see you at the show.
