Below are some Ghostbuster highlights / notes I took from the "This Flippin' Podcast" interview with John Trudeau.
Slimer toy: can be bashed w / cool lighting affects (referred to pro version)
Subway on pro: subway not possible on pro due to cost restrictions
On pro fun: Surprised how much fun pro is to play, said it turned out so well
Design: Starts with LE design and then take items off, easier to take things off then to build / design in. He said he loves the design process, the geometry.
Ramp that drops below playfield / lock on premium / LE: There's a divertor underneath, ball goes down and can get diverted into a 3 ball trap, balls get's released by a vertical up kicker (sounds like the right scoop). Sounds like a lot of testing went into design to make sure it works correctly. If lock is not lit the ball just comes back up. He said he's been thinking about it for 10-15 years.
Ball locks on pro: Virtual ball locks on pro
The steep left ramp in the back: Had to be that height to generate the speed needed for the ball lock
Magnetic slings on premium / LE: Tried them once before but the game never made production, thought with "ghosts" handling the ball that it sounded like a good idea to put in the game. Said they work pretty well, not like a conventional kicker. There are sound affects + flasher lamps that can go off when they are activated.
Double inlanes: hasn't seen them on a standard body game. Wood removed on left side to fit them, a steel plate there instead.
Flipper gap: Game has the traditional Troudeau flipper gap
3 ball captive ball toy: there's a post that captures the ball, hit 3 times, get all 3 balls on other side, post comes down, gravity feeds the balls back.
Second captive ball: Another newton ball toy, since there are no posts on the sides of the captive ball it doesn't have to be hit straight on to move the captive ball.
Asked which model would he pick: Troudeau said the premium, joked about not being a big fan of green.
Artwork: Sounds like he and Stern really liked working with ZombiYeti. Also hinted at him working with ZombiYeti on his next game!
LCD: It's coming but needs to be done right and be reliable. He said it's nice to have but he doesn't look at the display unless the ball is stopped.
Peppers ghost / LCD toy: Joked about Disney doing it for years on the Haunted Mansion. Said it was designed specifically with Ghostbusters in mind. Opto picks up the shot.
Code: Said Dwight is doing code with support from others. Mentioned the code is very good and will get better. Mentioned how each programmer has their own style.
Speed: He said the game is fast and brutal. He joked about it being a problem right now during testing, said the game screams.
Right ramp on pro: Ball returns to right flipper. George Gomez suggested the idea. There's a one way gate at top of curve, ball goes up over some rollover switches, strongest shot hits gate and the ball goes back to the right flipper.
The theme: A theme designers dream about, said "what don't we put in the game", made it easy
Working with Ernie Hudson: Mentioned he's easy to work with, very enthusiastic guy
Homage for Harold Ramis: They are trying to come up with something, would need approval from his estate and the studio
