I remember playing all the games in my personal collection. I collected them as they remind me of the "good old days", or they are simply brilliant players.
One game I MUST HAVE is a GTB "Rocket Ship". Since digging into the past, I found out this was part of the first shipment of Pinballs to Australia. I can't remember playing it. I don't care how it plays, it will be a sentimental decision.
Spiderman is an obvious choice as it is a great game by Stern before the cutbacks.
Breakshot is a brilliant game. Set out like and EM with good rules and humor. I VERY underrated title.
