Love the game. Diverters, Sanctum, Battlefield, 3 flippers, tight eject hole to start a scene, there just is no other machine like it. Nobody can say that it is a clone of another game.
People can argue all they want, but being based on a "B" movie really hurts the value.
Only "B" movie that has translated into an "A" pin is TAF- but I really don't know if that counts as it was a big enough movie to have sequels and it did pretty well profit wise. Not really a "B" movie, especially if you compare it to Congo or JM.
Theme and appeal have a huge impact on value and how collectible a pin is. Really can't think of any other pin that has so many alternate translites made.
