User blog comment:An Emerald/Group RP Idea Desert Island/@comment-24617443-20151027135850

How about having this a sort of survival game created by a mastermind who planned a plane crash of a group of people. The mastermind traps them all in a deserted island where the survivors' ultimate goal is to survive, while also completing all of the mastermind's tasks.

With that you can implement the rewards thing, along with creating scenes that may cause one of the three things you talked about to happen.

This is just an idea I made up though when I read through yours, Eme, so its your decision on how it goes out. I just wanted to suggest something.
