I have a Bally Atlantis, which is actually a really good pin. But it's quite simple.
The simplicity and the rapid zooming of the ball around the playfield is actually quite entertaining. It's genuinely fun to play.
It's surprising how often that my TZ sits unused while people camp out on the Atlantis. I'm not just saying that, my TZ probably gets the least amount of play, especially when my party guests are playing.
(And no, I'm not saying that to pump the value of my Atlantis, I'll never sell it. I love the total lack of Political Correctness of it.)
