the Murder Game is where I got most of my ICB inspiration from they were given a fictional series of murders to "investigate" and there was a team leader, who decided which 2 teammates were least helpful (or if they lost a task, he had to go) to be sent to some spooky dark place and either be "killed" or find a clue

only difference from ICB really was that none of them was the killer, they were given a cast of actors to interview and it was one of them
