Task: Question Answering
Input (English): passage: Fallout 2 was released in 1998, with several improvements over the first game, including an improved game engine, the ability to set attitudes of non-player character (NPC) party members and the ability to push people who are blocking doors. Additional features included several changes to the game world, including significantly more pop culture jokes and parodies, such as multiple Monty Python and The Hitchhiker's Guide to the Galaxy-referencing special random encounters, and self-parodying dialogue that broke the fourth wall to mention game mechanics. Fallout 2 takes place eighty years after Fallout, and centers around a descendant of the Vault Dweller, the protagonist of Fallout. The player assumes the role of the Chosen One as they try to save their village, Arroyo, from severe famine and droughts. After saving the village, the Chosen One must save it again, this time from the Enclave, the remnants of the pre-war United States Government.
