1) Maiden Premium
This game got me back into pinball and was the first pin I bought NIB. Great code, great music, amazing callouts, and a ton of fun shots. Has more plays than any other machine in my collection and still the one I play the most.
2) Metallica Premium
My second NIB purchase. Deep code, great music, fabulous callouts, and can humble any player with the brutal outlanes. Has made me a much better player.
3) Eight Ball Deluxe
Simple game with amazing shots. Has that "one more game" appeal despite it's simplicity.
