Gameplay

In The Sims 2, players control characters called Sims, as they interact with their virtual environments, engaging in activities and forming relationships in a manner similar to real life. The Sims 2 does not have a defined final goal; gameplay is open-ended. They do, however, have life goals, wants and fears, the fulfillment of which can have good or bad effects. There is also a wide-range of cheats to be used.

Sims

Sims are the characters a player controls, and are the main drive for The Sims 2's open gameplay. A player's Sims can experience a life generally reflective of reality through events such as working, marrying, having children, having children out of wedlock, adoption, homosexual relations, affairs, partying, eventually dying and others.

Physiology

Like humans, Sims operate based on certain drives: they have needs, develop dreams and goals, and exhibit personality. They can progress through six life stages: baby, toddler, child, teen, adult and elder (the expansion pack The Sims 2: University has an additional life stage, Young Adult, for Sims who choose to attend college). Sims die naturally after a certain number of days in the elder life stage, determined by how high their Aspiration Score was when they first became Elders. The different life stages present different challenges that the player must overcome, such as the slower movement of Elders, children not being able to cook, and constant crying of Babies.

As in the original game, Sims are driven by their Needs. Sims have up to eight Needs (or "motives") depending on their age, ranging from tangible needs such as "Bladder" (the need to urinate) and Energy (the need to sleep), to more ephemeral qualities such as "Social" contact and a pleasant "environment". These needs are displayed graphically with meters that change from green (full) to red (low), and a Sim with an empty meter will either require or insist on action which fills it (for instance, if the Hunger meter is low, a Sim will go to the refrigerator and "stuff face", or the user can direct them to cook something). Some empty meters also cause actions (a Sim with an empty Energy meter will pass out; a teen, adult, or elder Sim with an empty Hunger meter will die (starving children and toddlers will be taken by a social worker); a Sim with an empty bladder meter will wet himself). These Needs are compiled into an overall "mood" meter, whose color is displayed by the diamond (called a "plumb-bob") that hovers above the active Sim's head.

New to The Sims 2 is "Aspiration", roughly analogous to self-esteem or life satisfaction. As toddlers and children, Sims aspire only to "Grow Up", but upon becoming teens, the player assigns to them one of five life aspirations: Family (befriending family members, marrying and raising a large family), Fortune (wealth and prestige), Knowledge (both book learning and life experience), Popularity (friends and socializing) and Romance (frequent and varied romantic interactions); with the Nightlife expansion, a sixth Aspiration was added, Pleasure (wanting to live life to the fullest). Each Sim has wants and fears that correspond to his or her aspiration, stage of life and present circumstances.

When a want is achieved, such as to "make a friend", aspiration points are allotted to the aspiration meter; conversely, when a fear is realized, such as the death of a spouse, aspiration points are penalized. There are six levels to the meter: the highest is platinum, then gold, two levels of green and two of red, with the meter depleting a small amount every few hours. Aspiration levels, along with "mood", determine complaisance: Sims with a platinum meter are fulfilled, docile and more willing to perform tasks they dislike, in addition to having their mood meter full ("Platinum Mood") regardless of their individual needs; Sims with red meters will often experience nervous breakdowns and require treatment from an automatically-summoned psychiatrist. Aspiration levels also determine the length of time a Sim will live as an Elder before death. Finally, the Sim's lifetime total of Aspiration points are recorded by the game, and can be used to purchase special objects that possess unique effects, such as providing free money or altering lifespan.

Personality is a quantified way of measuring a Sim's behavioral characteristics. There are five personality traits, which players can allocate 'points' into to control that Sim's personality; for example, a Sim can be active, lazy or somewhere in between the two extremes. These traits determine how fast a Sim learns skills, the rate at which specific needs decay, the types of interactions a Sim will autonomously engage in, the likelihood of accepting certain interactions and the likelihood of bringing home a friend from school or work.


All Sims communicate in Simlish, first introduced in the original The Sims game. Simlish is a mix of several languages that communicates a Sim's emotions or reactions using tones of voice. This extends outside of characters; songs heard on the radio are also sung in Simlish.

Lifestyle

A Sim's life is very similar to a human's: after passing through infantile stages, he or she attends school, makes friends, may have a regular job, and achieve goals. Children must go to school or risk getting low grades and being taken away by a social worker. A Teen, Adult, or Elder Sim may have a career to earn a regular salary. Advancement in career tracks, such as business and science, requires achieving certain skill levels and maintaining a certain number of family friends.

Sims form two kinds of relationships with one another: daily and lifetime. Daily relationships are influenced by recent interactions with other Sims, while lifetime relationships are reflective of a pair's relationship as a whole. Lifetime relationships strengthen over time, while daily relationships weaken without recurring interaction. Romantic relationships are realized through marriage, both heterosexual and homosexual.

Sims can die in several ways. If a Sim reaches the end of the Elder life stage, he or she will die of old age. Sims can also meet premature ends by various means, such as electrocution, starving, disease, fly swarms, fright, fire, drowning or death by satellite. Sims leave behind tombstones or urns, which are typically possessed by their ghosts. As long as the memoriam is left on the lot, ghosts will haunt the household. Ghosts make it harder for a Sim to live by waking up easily frightened Sims, and can also scare a Sim to death.

After death, a Sim is no longer controllable and will be removed from the control interface. Death is carried out in The Sims 2 by the NPC Reaper, equipped with the uniform scythe and robes (not to mention a clipboard and cell phone). Sims can be saved from death (except dying of old age) if a friend begs the Grim Reaper for mercy. There is a better chance of saving the sim if there is a higher daily and lifetime relationship.

Other characters

There are three types of non-playable Sims:

• "Townie" Sims are those which are roughly equivalent to playable Sims, having jobs and other characteristics of a playable Sim, except they do not live on an actual lot. They populate the Community lots and can be interacted with just like any other Sim. With certain exceptions, any Townie may become a playable Sim if he or she accepts an invitation to move in, to be joined, or to be married.

• Non-playable Sims that perform specific functions are called NPCs. NPCs can be hired to work for residential lots as maids, nannies, and gardeners. There are also cashiers who work at community lots, as well as NPC Sims with special tasks, such as Firemen. Most NPCs may become a Playable Sim through union or moving in. Their role, now empty, is automatically filled by a new NPC.

• Special Non-playable characters are the Grim Reaper, Therapist, Social Bunny, Mrs. Crumplebottom, Stinky Skunk, Penguin, Headmaster, Social Worker, Repo Man and Bigfoot. Each of them have a special behavior.
