The whole planet [specify location and time]went silent as humans suddenly started disappearing. You are the only one left...or so you think. You find that, despite everyone gone, all the technology is functioning. Every house has electricity, running water, heating, etc. Shops are stuffed with food, cinemas are running, clubs are playing music, etc. You are free to do whatever you want. You may find someone else to explore and live out your wildest fantasies with. Good Luck
