The Sims 3
The third mainline Sims game, which places households in a seamless open neighborhood where unplayed Sims keep living, and replaces personality sliders with up to five traits and mood with stacked moodlets.
core loop
pick traits and a lifetime wish -> moodlets from events stack into mood -> wishes and opportunities appear -> act across the open town -> earn Lifetime Happiness for rewards -> story progression advances other households
design notes
Neighborhoods are seamless worlds, so Sims walk between lots without loading screens on PC, and Story Progression keeps households the player is not controlling aging, working, and forming relationships. Personality is a set of up to five discrete traits that unlock and bias interactions, and mood is the sum of moodlets, timed modifiers with named causes. Fulfilled wishes pay Lifetime Happiness points spent on Lifetime Rewards, replacing the wants and fears of The Sims 2. Off-screen story progression and wish generation are captured by the offscreen-life-progression and aspiration-wants mechanics.

Moodlets are named, timed mood modifiers (for example Nauseous during pregnancy) whose sum sets mood, which affects performance at work and school.
Needs decay
Six motives (Hunger, Bladder, Energy, Social, Hygiene, Fun) decay and spawn negative moodlets when low.
Personality traits
Adult Sims hold up to five traits chosen from a list, replacing the point sliders of earlier games; traits add exclusive interactions and bias autonomous choices.
Agent skills
Ten-level skills such as Logic, Cooking, Painting, Gardening, Writing, Guitar, Athletic, Handiness, Charisma, and Fishing feed careers and opportunities.
Aspirations and wants
A Lifetime Wish is chosen at creation and short-term wishes appear from traits and events; fulfilled wishes pay Lifetime Happiness points spent on Lifetime Rewards.
Career ladder
Twelve base careers that branch around level 6, plus part-time jobs; a performance style (Work Hard, Take It Easy, Suck Up to Boss) trades mood against promotion speed.
Daily schedules
Jobs and school run on fixed hours at rabbit-hole buildings, structuring each household's day.
Building placement
Build and Buy modes with Create-a-Style, which recolors walls, floors, objects, and clothing with any pattern and material.
Modding API
Script mods load as packages, with frameworks such as NRaas, alongside custom content.
Off-screen life progression
Story Progression keeps households the player is not controlling aging, working, forming relationships, and moving around the open neighborhood; it can be switched off in the options.
Smart objects
Objects advertise motive, skill, and fun gains; traits bias which advertisements a Sim picks.
Social exchanges
Conversation menus offer trait- and mood-gated interactions whose acceptance depends on relationship state.
Villager requests
Opportunities arrive from neighbors, community lots, and jobs, such as skill requests or overtime, and pay cash, raises, or relationship gains.
