I've been doing a series where I make 16 or more characters and have them do a Big Brother season. I usually control the competition wins (except for Season 7 which I did random.org competitions) based on the narratives of each character, and what I think would look best for the story. I have people make alliances, final two deals, backstabs, veto usage, nominations, based on how I think their character would interract with the rest of the cast.
So far the stories have panned out to produce 5 female winners and 2 male winners, with one winner coming close to winning the game twice.
Anyways, just putting this out there in case anyone is interested to read!
