In our campaigns at school, it is total chaos. I have one party. They are bloodthirsty.The second I describe the setting, it turns into The Hunger Games. They had amnesia, so they didn’t know where they were. NPC came up ( he had a map he was going to give the characters) and is slaughtered. This is so funny by now that I decide the map on his belt is enchanted into place. Then the elf ranger kills the dragonborn sorcerer. This is when I decide that this is  Hunger Games, except that people who die are resurrected, then put back in the arena. I need ways to kill them to keep it new and exciting!
