Non-playable character

Non-playable characters (NPCs) are characters that cannot be played by the player from the game's start. They are in every Sim game: The Sims, The Sims 2 and The Sims 3. (While townies are considered to be a class of NPC, they are largely outside the scope of this article.)

There are two main types of NPC; ones that through relationships and/or simple cheats will be able to be playable characters without any programming errors and ones that were specifically not meant to be played. In The Sims, all NPCs, other than the townies, are of this second type. Sims cannot build relationships with them, and most either can't be interacted with at all, or only have a few interactions that are related to their function. In The Sims 2 and The Sims 3, most NPCs can be interacted with, at least when they're not on the job, and Sims can build relationships with them. Also, some may appear on community lots, where they can essentially be treated as townies.

The Sims
Except for the townies, NPCs in The Sims are not full-fledged Sims. They have special character files which contain their names and define their appearance, and which control what they can do and how (or whether) they can be interacted with.

Service NPCs
These NPCs can be hired to perform services around the house.


 * Maid: She cleans up around the house and lot, and does most housekeeping. Comes every day.


 * Gardener: She waters indoor and outdoor plants. Comes every 3 days.


 * Repairman: He fixes broken objects, unclogs toilets, and even replaces light bulbs. Comes whenever called.


 * Butler: He comes every day, and will stay for most of it. He will either do household tasks, or call other NPCs to do them.


 * Caterer: He will refill the punch bowl, restock the buffet table, and clear empty plates. Comes when called, and leaves around midnight.

Other NPCs

 * Nancy the Paper Girl: The most commonly seen NPC in the game. She appears at 9 am every morning to deliver the newspaper. If a family has a dog, the dog may scare away the paper girl, but she will deliver the paper first.


 * Postal Woman: She appears every 3 days to deliver the bills, which she places in the mailbox.


 * Repo-man: If the player doesn't see that a family pays their bills, or if a family doesn't have enough money to pay them, the repo man will show up and use his repossessing gun to absorb some of the objects in their house to cover the bills.


 * Social Worker: If the player doesn't see that babies are taken care of, the social worker will appear to take them away.


 * Burglar: Whenever every Sim on the lot is asleep, the burglar may sneak in and steal their possessions. Players can either have a Sim call the police, or buy an alarm. With the alarm installed, the police will arrive instantly. If the police are called over the the phone, it may take too long for them to arrive, and the burglar may escape.


 * Entertainer: The Entertainer is introduced in House Party. Buying the large cake available in Buy mode under Miscellaneous and clicking on the option "Buy Male/Female Entertainer" causes the entertainer to emerge from within and start entertaining the guests. Be careful, though, because the entertainer might stir some jealousy from other people at the party.


 * Mime: Introduced in House Party, the Mime will show up at a party if it is going very badly. While he will try to raise the mood a bit, he isn't very good at it. The Mime has been known to steal objects around the house. He will leave only when the party gets better.


 * Party Crasher: Also introduced in House Party, party crashers will arrive during mediocre to fairly good parties, and have been known to destroy objects, though they do not always do so.


 * Drew Carey A real life celebrity who shows up as a reward for a great party.


 * Santa Claus: If one has a Christmas tree up, and a plate of cookies on a table near the fireplace just before midnight, Santa Claus will show up while the Sims are sleeping. He'll leave a "gift" for each of Sim in the family, plus an extra special present, which could be any item.


 * Obsessed fan: Introduced in Superstar, Sims can attract unwanted attention if they achieve 3 stars of fame or more. The obsessed fans will stalk the Sims wherever they go, at home or at work. They leave 'special presents' for the Sims - black roses. They also paw through garbage cans, and will steal any awards that Sims have won for acting, singing or modeling. Awards can be protected by placing them in a room with the Zeddy-Lock Celebrity Security Door, as Obsessed Fans cannot go through that door.


 * Grim Reaper: Introduced in Livin' Large. Grim shows up whenever a Sim dies. What happens next depends on his mood. If Death is in a bad mood, he will take the corpse with no way to prevent it; if Death is in a good mood, the player can direct another Sim to challenge Grim. If he accepts, he will play rock, paper, scissors with that Sim, or will put a die under three cups and mix them up. The Sim will have to try to pick the cup which holds the die. If the Sim wins the game, or picks the right cup, the deceased is brought back to life for a second chance, but if the Sim loses/picks the wrong cup, Death will either take the corpse or, be nice and create a zombie.


 * Animal Control Evan: Introduced in Unleashed, he is the neighborhood's animal control officer. When Animal Control is called, he will come to remove El Bandito or Henri LeStanc. He cannot be called unless one of the two is on the lot.


 * Marilyn Monroe, Christina Aguilera and Avril Lavigne are introduced in Superstar. They will appear at random on lots in Studio Town.

Community lot NPCs
All community lots in The Sims spawn a janitor, who does general clean-up and repair work on the lot. Community lots on Vacation Island, and in Studio Town and Magic Town, also spawn a "lot director" who can provide information about some aspects of gameplay. On Vacation Island lots, a costumed mascot will arrive in the morning and leave at night, and an indoors maid will appear if a hotel desk is present.

Other community lot NPCs such as clerks, cashiers, waiters, etc., are spawned by specific objects.

The Sims 2
The Sims 2 NPCs are much more colorful. For starters, basic NPCs can be interacted with in the same ways that other Sims can, at least when they're not on the job. They can be talked to, befriended, invited over, married, etc. They can be male or female, and each has a different face, hair color and name. They generally make more logical decisions, though there are exceptions. A neighborhood will usually have three NPCs of any given type (maid, etc.). When an NPC becomes playable, a new NPC will be generated to take the old NPC's place.

Townies
Townies form the largest class of NPC. Townies wander around the neighborhood or randomly walk by Sims' houses. There are many types of Townies in The Sims 2: see Townie for more information.

Service NPCs
Service NPCs are NPCs that help Sims around the house.
 * Maids: Maids clean the house and do most of the housekeeping. They come every day.
 * Gardeners: Gardeners clean Sims' gardens, pull weeds, water flowers, trim shrubs, and rake falling leaves. They come every three days.
 * Nannies: Nannies take care of babies, toddlers, and children. The player can have them track the calling Sim's work schedule. It's important to hire a nanny if there's no teen or older Sim in the house, as the social worker will take children who are left unattended. Nannies are also needed when going to a community lot or going on vacation would leave children home alone.
 * Bartenders: Sims can hire a bartender if they have a bar in their home. They are paid by the hour. Bartenders are also Community Service NPCs.
 * Exterminators: Whenever a Sim's house is infested with cockroaches, they can call exterminator to get rid of them.

Sims can also ask the Matchmaker for a blind date. In FreeTime, the Gypsy Matchmaker may deliver a Dusty Old Lamp to Sims with high enthusiasm in a hobby, and high Lifetime Aspiration.
 * Obedience Trainers: Obedience Trainers train adult pets and sell Lycanthropic-B potions.
 * Butlers: Butlers take over almost all of the Service NPCs work. So, Sims no longer need to hire every single Service NPC for housekeeping. Butlers are very costly, so players should mind a family's budget before having them hire one. Butlers don't take care of some problems, such as cockroaches, fires, or burglars. Instead, they call the appropriate NPCs.
 * Landlords: Landlords are assumed to be the owners of the apartment lots. Sims can pay the weekly rent directly to the landlords or by using the mailbox. Sims can lower their rent by making friends with them. They will garden and clean the common area in an apartment lot.

Emergency NPCs
Emergency NPCs arrive immediately after Sims call them on the phone, or when summoned by an alarm.
 * Police: Police can apprehend a burglar, but are not always able to. They also appear when a Teen is caught sneaking out or a party lasts until midnight. Sims also need to call the police when their Teens or pets run away. When Sims adopt a pet, a police office will bring the pet. In University, a police officer wearing a llama blazer will "arrest" Sims who are to be inducted into the Secret Society.
 * Firefighters: Firefighters are always able to put out fires, though when a fire is very large, they sometimes call for help from other firefighters.

Professors may appear on community lots outside of the college sub-neighborhood, and sometimes appear on secret hobby lots.
 * Coaches: Coaches sometimes appear on a lot, whether it's a college community lot, dorm, Greek house, or even a private rental house. They will yell at Sims and try to force them to work out, but can often be avoided.

They may appear on any lot in a college sub-neighborhood. The llama mascots will autonomously do the school cheer in front of any Sims. The evil mascots will do pranks, will irritate and annoy Sims, and may even do some flirting. When the llama and cow mascots see each others, they will fight. The llama mascots will always win because their Body skill is maxed, while the cow mascots have little or no body skill.

 * Stinky Skunk: Stinky Skunk wanders around residential lots. Sims may pet him, watch him, or chase him off, though the former two actions will cause him to spray them.

 * Penguin: Penguins may appear at a house if it's snowing, there's a snowman in the lot (Whether finished, unfinished, or broken), or a fish is mounted on the wall.

A fire can also be started by lighting a fireplace with flammable objects nearby, or a birthday cake can spontaneously combust.
