Most out of the box storyline projects

Hi All, I was wondering if people would be willing to share their most out "of the box/pushing the system to its limits" storyline samples. I have just been tasked with creating a gamified lesson in storyline that mimics the game "the Sims". It includes several "happiness" meters based on the user's responses, a timer that will change the states of each character based on how long it takes the learner to respond and a few other bells and whistles...I know I have seen some really creative stuff here in the challenges, but was wondering what other really cool/different things others have created if you don't mind sharing a link or even just the concept.
