Discussion thread:
Metallica
Multiballs and mini-wizard modes.
Wizard of Oz
Total Nuclear Annihilation
JJP Pirates of the Caribbean:
The chapters aren't really modes. It's sort of "multiballs and mini-wizard modes", like Metallica.
Jurassic Park (Stern):
All the dinosaur modes are variations on the same mode. That's really different.
Wonka:
Mostly not a mode-based game.
JJP Guns N Roses:
Interesting multiball-infused modes, with the add-a-balls and everything.

So my questions are:
Did I categorize these games correctly?
What do you think of these games and their rulesets?
Keith P Johnson games appear 3 times on this list... has this mad genius soured on typical mode based games?!
Did I miss any?

To my mind, the descriptive value of saying that JJP POTC is not a mode-based game is so that people know that the bulk of the rules are not found in the chapters, they're found in the multiballs, the mini-wizard modes, etcetera.
