I'm going to be a real buzzkill on this one. I'm a serious player of EM machines, and I avoid all games that don't have a standard flipper layout. Kind of like the way playing baseball really messes up your golf swing, I find that these 'off' games interfere with my well established and practiced day-to-day techniques. Just a couple of games of waiting for the ball to bounce off something that's in between my flippers, and my timing and reactions are shot for a while.
