Originally for our game "Paparazzi", we wanted a survival type single player mode that took place in an overworld. The player was assigned to run around the world and achieving tasks to gain "Fame" in order to become a star! All the while pressuring paparazzi would appear to try and catch you in the act.
It was pretty cool, but we unfortunately had to scrap it due to time constraints and design problems. But! It does look awesome and it was a lot of fun to take existing assets to create something totally new!
