Quoted from Rarehero:

Those are all neat options, but what people truly want to see in pinball are “holy shit, that’s cool!” mechs & features. Watching something living & magical happen on the playfield. The MM castle interactivity & explosion...Addams’ Thing grabbing the ball...Dr. Who’s Time Expander & its 3 level reveal...Stern’s POTC ship getting destroyed & sinking...the closest thing in a decade is probably Stern JP’s T-Rex - a really well animated, exciting “living” interactive creature (although it’s not on the Pro lol).
LEDs & LCDs are OK, but expected in a modern electronic product. We want to see something absolutely unexpected that we want to then see happen repeatedly cuz it’s so cool.

Quoted from usandthem:

I had my first "big display" game with Stranger Things. I have to admit that I loved seeing scenes from the show. I love how the more you did to make it through the mode, the more you got to see of the scene. That was cool. But, I'm with you. I play pinball to see cool mechanical stuff happening on the playfield above all else.
