i thought a friday the 13th machine would be cool. you could have the "teleporting killer" toy, which would be a random subway system with several kick outs. the ball would randomly come of out of one of the kick outs, maybe with a brief indicator flash light. maybe have all the lights go out momentarily so the playfield is dark to build suspense.
you could also have building modes. first would be kill jason's mom. then kill zombie jason. then collect hockey mask. then kill hockey mask jason. then ressurrect jason. the wizard mode would by trying to kill jason, but in the end, he lives and the machine wins, which is how every pinball game eventually ends.
could also have the creepy 'chick-chick, ha-ha' sound going, getting faster and fast, louder and louder.
just some ideas.
i also love the idea of reanimator because it's a great movie and has some great comedy relief. "what was i supposed to do, leave a note? sorry, cat dead, details later?"
