Quoted from PEN:To me its a head scratcher. I liked the game right from the start, but did not like it enough to buy it. Its a good game, but it might be the most over hyped game on pinside. When I look at my own collection and realize I would have to sell my mintish JP and SST + cash to buy an IM..... Well its just not that good to me. If its a rarity coveting situation, my SST fills that need, and I prefer it anyway.
To me rarity has nothing to do with it... It's just a damn fun game! IMHO no other pin has the "just one more game" effect more than IM, I literally finish a game and am pawing for the start button as soon as the 3rd ball rolls into the trough.
