I've put enough games on my BM66 and I've watched enough of the TV show with my family - because otherwise, how would the kids understand the pin? - that I've really come to a deeper appreciation of the mode design.
Like how the Mad Hatter shots in the The Contaminated Cowl mode are pink - like Batman's cowl.
Or why sometimes the mode shot is the GADGET targets - because in the episode the mode is based on, Batman is actually using a gadget. Maybe I'm a little dense, maybe not. But it took watching the Catwoman episodes The Purr-fect Crime/Better Luck Next Time to understand the Batman was using both his earplugs and high frequency generator at the point the pin was lighting the GADGET targets. I guess it's hard to watch the display and play the game at the same time.
And how the magnet is used in Fine Feathered Finks/The Penguin’s A Jinx - because in the episode, Penguin uses a magnet to trap Batman and Robin.
Some lost opportunities that I've noticed so far, just minor things -
* The Purr-fect Crime/Better Luck Next Time - Robin has a great one liner - "Catwoman, you are not a nice person." - at the point he is on the teeter-totter. That would have been good for a mode shot.
* Surfing Joker - It would be great if the mode switched to GADGET targets at some preset % complete so that Batman could use his shark spray.
* Chief O'Hara - I need more of Chief O'Hara being an idiot. Maybe a fourth minor villain wizard mode?
We have 80+ more episodes to watch and thousands of more pinball games to play, so I'm sure I'll find some more great subtleties in the game and moments from the show I wish were in the game.
