Quoted from Aurich:Isn't there a pretty successful Ghostbusters slot?
There sure is.

It was successful enough that they apparently made a sequel (http://protoncharging.com/2012/03/28/igt-to-release-second-ghostbusters-slot-machine/). I played the original a couple years ago and it was actually really cool. The reels had a subtle 3D affect that actually worked and it had a bunch of custom animation and minigames. The big 50" screen on the top caught the attention of passers by well and was also used for some group events that applied to everyone playing one of the linked machines (if they qualified). If I recall there were speakers in the seats, too.
Both that one and a Dark Knight one that looked like it was on the same platform were attracting a lot of attention when I was in Vegas. They were usually the "showcase" games by the casino entrances. Having not played slots for about 10 years, I was impressed. I'd love to see a Stern game with similar HD animations (but yes, Ghostbusters would be awesome).
Quoted from Aurich:Wonder if slot themes are in any way comparable to pin themes when it comes to audience.
I'd think the same general principles would apply as far as wanting something with broad appeal. Although I guess there are more slot machines being made than pins these days so they can afford to go after specific markets a little more (e.g. Sex and the City slots). With how much these big 4-chair, 5-screen setups must cost, though, you'd think they'd need to know it would be popular.
I wonder if that's how the Wheel of Fortune pin happened. Though I think that's a theme that seems better suited to slots than pinball.
