I know it's another toy but Doctor Who's Time Expander takes the cake for me.
It has to be the most interactive toy in pinball. It moves between three levels: two ball lock saucers and a stand-up target; a bank of mushroom opto targets that absorb momentum; three scoops with dalek doors.
It is a very effective centre shot because a newbie can experience most of what the game has to offer just by shooting up the middle. Getting all the way to multiball is a rush. We all know that newbies only ever shoot up the middle!
Of all the games I've owned I think DW is the only one that most newbies who have played it have achieved multiball reliably through their own effort. And because one of my favourite things about pinball is sharing it with others, this is a valuable asset.
