This expansion introduces a host of new NPCs, including Servo, the Tragic Clown, and the Grim Reaper. Leave cookies by a Christmas tree and a fireplace, and Santa Claus will visit and tuck presents beneath the tree. The Tragic Clown drops in on depressed Sims who own the Tragic Clown painting, always failing miserably to cheer them up. Sims can even catch an illness from a bite by the guinea pig the pack adds. When a Sim dies, the Grim Reaper performs the final rites — and a living Sim can plead for that Sim's life, leading to one of three outcomes: death, resurrection, or transformation into a zombie.
Livin' Large packs in plenty of new objects, too, such as a crystal ball, electric guitar, chemistry set and magic lamp, some with their own NPCs attached — rub the magic lamp and a genie appears, while a Servo arrives with a particular booth. The expansion also adds multiple new neighborhoods, letting players maintain up to five fresh ones.
