Since I started acquiring pinball machines a few years back, I strived for variety throughout the years and also picked up some of my favorite machines from the past. A few have come and gone, but I am very happy with where my collection is now.
As I research each game, I started noticing that not many were designed by the same guy. So I looked into it and found 18 different designers, not including other members on the team, were given credit for the 25 machines I have now. The most I have by one designer is four by Steve Ritchie.
Here is the list-
Besides the designers mentioned above-
Python Anghelo was given design team credit on Big Guns
Slash and Lyman F. Sheats Jr. were given team credit on GnR.
Greg Freres, Matt Coriale, and Dwight Sullivan were given team credit on No fear.
A couple of the above mentioned were on other machines design teams as well.
