Bring back the entire cast of a season of #Survivor or Big Brother
They know what happened the first time, they presumably all know each other, etc
For Survivor maybe shuffle the tribes? IDK. Big Brother would have different competition winners so it would be shaken up by that
So in a sense some people will be trying to stick with old alliances, some will be trying to fix old mistakes, some will be coming off of betrayals and blindsides from the original season
What types of players would do well on the second go? Past winners? Finalists? Early boots? Jury members?
