In terms of theme/license, AC/DC is a home run. Stern knew this. That's why they offered two LE models, a Premium model, and the pro. They knew they'd sell.
Theme is important. But it has to play great in addition to having a great theme. AC/DC does both.
I love the fact that AC/DC seems to have reached a good balance of speed and challenge, without being frustratingly difficult either. It still reminds me of IM more than any other pin in terms of how it plays (and that is definitely a compliment). Not saying IM and AC/DC are the same, just that the speed and difficulty are similar.
If I wasn't as excited about the potential for XM, I'd probably have a Premium AC/DC by now.
Well, hate to be confrontational, but acdc got the most attention above the A listers, and above Stern recent releases like Black SM, POTC, BDK, and TFLE.
I can't tell you why it gets attention. One guy, who hadn't played pinball in decades commented on liking the old classics like my ACDC machine.
The machine isn't dated by a movie, like BDK and BSM and POTC.
Challenge; Put a bunch of pins in a room, send some folks in who don't know which one they should like, and see which one they enjoy the most. If you have a ACDC LE, I bet that machine will get more attention than any other single machine by the majority of the participants.
