Keep in mind, just cause a game looks like a game don't mean any particular designer had anything to do with it.
They were churning out these games by the month, it wasn't like today when you get 2 new titles if you are lucky. And there's only so many places to put a pop bumper, spinner, and drop target bank.
Not that I ever really cared, but suddenly I am desperate to know who designed Aztec! There really isn't much to that one but it's fun ripping the spinner - I've gotten over 60 spins (!) on the one at PAPA.
