Data East did that a few times, Last Action Hero is one I've had that did it, I think Data East Jurassic Park does, probably others I can't think of right now.

Someone who's a Data East/Sega expert might be able to chime in with more. I can't think of any Williams or Stern games that do it.

Another DE where it feels like a real MB progression IMO would be Tales from the Crypt. After completing the left ramp for the first jackpot, and then the right ramp for the second jackpot, the animations on the DMD, firing up the chainsaw, getting chasing down by undead, and then slicing the head in two has to be one of my all time favourites.. but this goes further when you go for monster jackpot, where the tomb target rises, and you need to hit it five times, each hit gives you an add-a-ball, if you are able to complete it (spelling c-r-y-p-t), then you need to land a ball inside the tomb for the monster jackpot, where you see some straws slurping away some cranial juices as your victory on a monster collect. The monster is what feels like that evolution.. just such a great additional rule that is quite challenging.

One of my favorite features!

Tommy too. Seemed to be a DE thing.

Raptor mb in Sterns JP also does, since it's a throwback to the DE one

A lot of games now have victory laps which isn't quite the same thing but it's at least a second stage that you can reach and some have bee choreography

Apollo 13

Medieval Madness has Multiball Madness which changes pretty significantly depending on how many of the games other tasks you've completed. 2-4 balls, increased scoring, more Super Jackpots, the potential for Trolls, and lots of different callouts.

Addams Family

Yeah, I was thinking about MM, not sure if I am misremembering, but I thought you could add-on trolls madness as well completing it during the main madness you started? Definitely fun to try to build it up as much as possible before starting.

Trolls can be brought in during MB for sure. Then when you complete its that’s an add a ball and adds troll madness to the pile.

Besides from Trolls it doesn't really 'evolve' during the multiball though. I'd say the castle multiball is actually closer to this. 5 ramps, then super jackpot, then all shots lit, iirc? at least 3 stages

What about Terror of Mechagodzilla or Gappa Angry? I think those are my favorite MBs of recent years.

Stranger things and the Trap em Demogorgon MB is pretty good too. 3 stages.

Wonka is pretty awesome

Been awhile since I've had the game, but I believe he shouts, "live, live, live!" (taken from the scene in the film when the creature rises).

As for another multiball that may fit the theme of the thread, the Judge Dredd super game starts with a 3 ball multiball that evolves into 6 ball multiball once the drops are complete, which starts a 100M point jackpot objective. Certainly not as neat as MSF though.

Not a popular opinion but I hate stacking, which I think is easy and very lazy code - just bring an active mode into another one. A great sense of achievement for sure, if you're chasing points, but a confusing mess for everyone else.

I've 'evolved' this basic and over-used pinball rule into something more fun, which I call 'Power of Attack'. But you'd have to play my latest Avatar remake to experience it.

Pinball code has stagnated over the past decade, as the old timers recycle their own best ideas. But it doesn't have to be like that. Fresh young minds can unlock pinball's full potential.

Curious about the general idea? I mean, we already have the strategic multiball build up idea in madness. We have titles where the points are in seting up modes or starting modes prior to Mb. We have ongoing Mb rules.. Aab, incrementing jackpots etc. Evolving rules for Mb which is what this op is.

Stacking modes is practically part of the vocabulary of pinball, at this point -- more of a tool of design rather than the design itself. Always easier to call something "lazy" or "simple" instead of acknowledging what it brings to the bigger picture. Iron Maiden is a great example
example of a game where not every mode is conducive to stacking with every multiball, but players can discover synergies as they improve. This kind of personal discovery is GOOD.

It's hard for me to believe that a decade with Rush, Metallica, B66, Wonka, Dialed In, and all 4 Elwin games could be considered stagnant, but different stacks for different quacks, I guess.
