The Sims 2
Gameplay
From the neighborhood view, the player selects one lot to play, as in The Sims. There are both residential and community lots, but Sims can only live in residential lots. Community lots are where Sims travel to in order to purchase things like clothing and magazines, and to interact with NPCs and townies.
The player can choose between playing a pre-made inhabited lot, moving a household into a built-up lot, or constructing a building on an empty lot. One novelty from The Sims is foundations.
The player switches among the "live" mode (default) to control Sims, the "buy" mode to add, move or delete furniture, or the "build" mode to rebuild the house. Buy and build mode for community lots is locked when player Sims visit the lot but are available from the neighborhood view. It is also possible to import neighborhood terrains from SimCity 4.
The game contains some time-bound social challenges that provide a reward if successful. Sims can throw parties to gain aspiration points or invite the headmaster over for dinner in order to enroll their children in private school. Some expansion packs have new mini-games, like running a Greek house in University or dating in Nightlife. In Nightlife, each date is a challenge to keep both Sims as happy as possible while accumulating aspiration points. Various other expansion packs introduce supernatural characters which Sims can be turned into. This includes Zombies, Vampires, Werewolves, Plantsims, and Witches.
Sims
The main part of the game is to lead a Sim from the start of life to death. A Sim will be born when a female Sim and a male Sim try for a baby. The mother will spend 3 days pregnant before giving birth to a baby. Players can name the new Sim upon birth. The baby's appearance and personality will be based on the genetics of its parents (though the baby's appearance is hidden until it becomes a toddler). The baby will change into a toddler in 3 days, and 4 more days for the toddler to change into a child. After 8 days, the child morphs into a teenager, and will live 15 days before changing into an adult. After 29 days, the Sim will become an elder and eventually die, the length of the final stage depending on the aspiration bar when they age.
Babies, toddlers, children, teens, and adults can be advanced to their next life stage at any time during the 24 Sim hours before they will grow up automatically. For babies, this requires using the birthday cake. Toddlers, children, teens, and adults can use the "Grow Up" self-interaction. If the University expansion pack is installed, teens have the option to go to college, where they will be young adults for approximately 24 days. Aging can be disabled via cheats.
Players will need to build up talent badges, skills and relationship with other people, so that they can be successful in their career. A player will also need to make sure a Sim is happy and well by fulfilling wants (including lifetime wants, avoiding fears, and fulfilling motives).
Pregnancy, toddlers, teens and elders are new stages of life. Young adult is a unique age added with the University expansion. Teen Sims will become young adults once they are moved to a University, and will be adults once they leave campus, regardless of the reason. During Pregnancy, the belly does not expand gradually. Instead, every day, it "pops" to a bigger size.
Create-a-Sim
In The Sims 2, Create a Family is entered by clicking the "Families" button in the lower left-hand corner of the neighborhood view, then clicking the large "Create New Family" button. Clicking the button labeled "Create A Sim" will expand a tab which has the "Create a Sim" and "Make a Child" icons. "Make a Child" will be grayed out unless the family contains an adult male and adult female. Clicking the "Create a Sim" icon will generate a random adult Sim, who may be male or female which can be edited by the player.
As opposed to The Sims, any age besides baby or young adult (which must be made in the University Create a Student) may be created. Instead of having to choose from already finished faces which include hair, it is now possible to alter the facial structure (e.g. widening the nose, thinning the lips, elongating the chin, etc.) and choose any hairstyle to go with it. Different eye colors and an additional skin tone is available for the Sims as well. If the Sim is older than a child, their aspiration and turn-ons/offs (Nightlife or later) may be determined. As in The Sims, there are five personality traits, and 25 personality points which can be assigned to those traits. However, in The Sims 2, all personality points must be assigned. Additionally, there are twelve pre-set personalities, one for each of the twelve zodiac signs. A zodiac sign will be set which matches the personality the player has selected for the Sim.
Additionally installed with The Sims 2 will be The Sims 2 Body Shop, which enables users to create items of clothing, make up, skintones and much more for all ages and types (e.g. Everyday, Formal etc.) This can be found through the Start menu, and going into the folder of the most recently installed expansion pack and opening up The Sims 2 Body Shop. It does not require any additional downloads.
Social interactions
There are several new social interactions introduced in The Sims 2. These new social interactions can create memories and can be related to certain age groups. Social interactions can come up in the Wants and Fears panel and can be dependent on the Sim's personality and aspiration. Sims with certain personalities may not want to complete certain social interactions.
Influencing
Influencing social interactions are introduced in the University expansion pack. A Sim is able to influence another Sim to complete a social interaction or a chore. Sims gain influence points by completing Wants and can lose influence points by completing Fears. The size of the influence bar depends on the number of friends that the Sim has. It also can grow in size with business perks from the Open for Business expansion pack. Influence was also in the Nightlife expansion but added nothing.
Chemistry
The Nightlife expansion pack introduces Turn-Ons and Turn-Offs. Teenagers and older are able to choose their turn-ons and turn-offs. These determine the chemistry that one Sims has with another in the form of lightning bolts. Sims can have up to 3 lightning bolts with another Sim. The higher the chemistry is that a Sim has with another Sim, the greater the chance for social interactions to be accepted. New turn-ons and turn-offs are introduced with the Bon Voyage expansion pack.
Fury
Fury is introduced in the Nightlife expansion pack and occurs when one Sim gets angry at another. During this time relationships with the Sim who is furious are harder to build. Also, the Sim who is furious may pick a fight or vandalize the home lot of the Sim they are furious with. Fury can be caused by another Sim burgling the Sim's house, getting fined after calling emergency services when there was no emergency, fighting, cheating on (the cheater or the Sim that was cheated with, often both) and more.
Reputation
Reputation, which is found in the previous sims game The Urbz: Sims in the City is reintroduced in the Apartment Life expansion pack. A Sim gains reputation by interacting with other Sims on community lots. Sims with higher reputations are more likely to gain perks such as free objects and job promotions.
Careers
There are careers that come with the game that require skills and a certain number of friends in order for promotion. Success in these careers unlocks career rewards and higher salaries plus bonuses. Sims also will receive chance cards. Correct answers to these chance cards will create rewards for Sims while incorrect answers could cause a Sim to lose its job. Nightlife and Apartment Life allow Sims to gain promotions through social interactions with other Sims.
