1. The Room
The Room won’t let any players under the age of 15 into their rooms, so you know they mean business. “The Cabin” is particularly grisly: Players must find their way out of a carnivorous serial killer’s home to avoid being consumed. “The Spaceship” offers an option for those who don’t like gore. Though you might feel an adrenaline rush as you track down astronauts taken captive by a potentially hostile interplanetary life force, there’s no blood or guts involved.
