We have 1 pinball machine - Lord of the Rings . We decided that 2 will be the number of machines in our house, and are playing a lot of newer games on location to determine which one to likely get NIB. (FYI, Star Wars (Pro) and The Beatles (Gold Edition) are top candidates so far due to theme and quicker ball times, but more research is needed...)
If Willy Wonka is released by JJP, my wife decreed that we would make room for a 3rd game.
I hope that one of the toys is the bed in Charlie's house, and we get to bash Grandpa Joe all day long. He's the real villain in that story.
