I played a Tron the other day sited, didn't do much for me, not sure if it was broken or working as intended, but when you launched the ball, if you didn't nudge the machine it would immediately drain right down the middle between the flippers! Not sure what I was doing wrong... But I must have pulled the plunger 100% back, launched the ball, drained, ball saved and repeat 5-6 times before it got into play by nudging it into the pop bumbers.
I agree with you mate,I think the game is a real dog.
