When Rainsford comments upon the cape buffalo being the most dangerous game (prey), in Richard Connell's "The Most Dangerous Game," Zaroff disagrees. He states that the prey on his island is "the biggest." Given the animal is not natural to the island, Zaroff must import it. Rainsford suggests tigers, but Zaroff states that tigers no longer pose a danger or challenge for him. Bored with traditional hunting, because it offers no challenge, Zaroff has "invented a new sensation." Having hunted every animal, in every land, Zaroff no longer feels challenged by the animals at his disposal.
This new sensation, the new prey, is man. Man, according to Zaroff, is the only animal capable of reason. Through possession of this ability, man poses a threat and challenge for Zaroff.
