AC/DC was an awakening for me. I never owned a Stern before and now I own three (four with South Park?). I played it for months on end and never got bored of it. I still love it to this day and proclaim it as the greatest pinball machine ever made. I thought Metallica would take the title as I am a bigger fan of Metallica's music and think it has better artwork, but AC/DC still holds the top spot for gameplay. Now I crave more Stern machines....
Cheers!
Adam.
