Chaotic Looseleaf
Disney themselves have iterated on this concept multiple times in the video game space; my understanding is that most of them revolve around "dungeons" related to major attractions that are usually rewarded by some kind of key (keys are a big deal to Disneyana although I've never completely understood why). Collect all the keys, open Cinderella's castle, complete the final dungeon, rescue Mickey.
