Twilight Zone for me. The Aladdin's Castle at Brookfield Square mall had one as well as one at a comic book shop in Pewaukee that I would go to about once a week back when I was in middle school. Getting the powerball and multiball was so cool on that game. The mini-playfield was great too. I also played a bunch of DE Star Wars and Jurassic Park, but TZ really got me hooked.
TZ was the first pin I bought back in 2004 and I still have it.
