Sims 2 Battle Royale location?

I've been thinking again about the possibility of a Battle Royale type story using the teen characters from Sims 2, and wondering where to set it. An abandoned Twikii Island, perhaps? The mean streets of Sims City? If anyone here has read the book or manga or seen the movie, I'd love to hear your thoughts on it. Or even if you haven't, what location do you think might make the most interesting battleground?
