i own tilt and enjoy it. on disk 2 there are some really cool bonus features. one of the best imo is an audio only round table discussion with roger sharpe and some of the design team.they reveal a lot of their personal opinions about pin2k,williams and other things in pinball. if you get the chance check it out. also check out pinball passion. its another documentary that is well done. its more like special when lit without the extreme personalities.i got both tilt and pinball passion on amazon fwiw.
