If you're American, or are just aware of pop culture, you've heard of Family Guy. The Seth McFarlane show hit airwaves in 1999, and is currently one of the longest running sitcoms in American history. So it only makes sense that Stern would make a family guy pinball, which came out in 2007.
The game was designed by Pat Lawlor–who created fan favorites such as The Addams Family and Twilight Zone–and features Flippers (5), Pop bumpers (3), 4-bank drop targets (1), Standup targets (9), Solitary drop target (1), Captive balls (2), Spinning target (1), Up-post between flippers, Mini-playfield, Multiball.
What did I think? Well, it was fun if only because it has the original voices from the show, and the mini Stewie playfield was charming yet difficult to score on. While I understand why people love it, I don't think it's worth the money it still demands. I think $4-5K is perfectly fair for this machine, depending on condition.
The game is fairly easy to find if you're on the market for one, but they will go for over $6k.
