I played this many times, it was in our office at Heighway Pinball. We were working on our own Playboy pinball game at the time (designed by Barry Oursler). Thankfully, the project didn't make it beyond my hard drive.....it was bloody awful.
Stern's game is ok fun I suppose, with some interesting shots. And who doesn't like looking at titties
More titties in pinball is what I say.
