The following games also make extensive (sometimes even exclusive) use of the d12:
Led Zeppelin at the Marriott
The Hellriders of Ernst and Young
The Best Little Whorehouse in Texas, the RPG
A Date with Natalie Portman, the RPG
ZARDOZ (The gun is good. The penis is evil. Go forth... and KILL!)
That's just off the top of my head. There are plenty more. Unfortunately those games are all published in Sao Tome and Principe and really hard to find in the US. I wouldn't be suprised if you can't find them in the UK at all. (And Yes, I'm kidding ).
