I'm an "OK" pinballer. Nothing great but I can keep the ball going and accomplish some modes and tasks during an average game. I felt my skill really plateaued and I was fine with that (I was still having fun). That all changed when I got my Shadow pin. The Shadow forced me to become a better player. There is just so many shots and having to control the diverters manually really keeps you on your toes. As a result, I find myself doing much better on all the other pins in my collection and on location. I thought this might be an interesting topic. What game(s) makes you a better pinball player and why?
