The Tragic Clown is a character that spawns if the painting of the same name is placed on the lot and an occupant is on the lot. Livin' Large introduces complex interactions with two non-player characters: the Tragic Clown and Grim Reaper. The expansion expands the default number of lots in the game by increasing the number of neighborhoods. Livin' Large also features five new career paths: Slacker, Hacker, Journalist, Paranormal and Musician. The 'Vibromatic Heart Bed' items allows a pair of sims in love to 'Play in Bed' once the bed is occupied and vibrating, providing a chance that the female Sim will become pregnant with a baby. Sims can contract a potentially fatal illness from a bite from the guinea pig included in this expansion.
Some interactive items feature additional effects and new non-player characters, including a magic lamp that, when rubbed, spawns a genie that can grant the player wishes with random good or bad outcomes, a chemistry lab that can create potions with positive and negative effects, including turning the drinker into a monster, and a robotic servitor that can assist with housework. Some items are decorative, and others are interactive.
Primarily a content-based expansion, Livin' Large adds 125 new items for sims to purchase in the 'Buy Mode' of the game. See also: The Sims (video game) § Gameplay Livin' Large introduces a number of new decorative and interactive objects to The Sims.
