Skills
There are several skill-dependent abilities, such as advanced social interactions available from high charisma, special songs for guitar players and appliance upgrades (self-cleaning, more TV channels, etc.) for high handiness. Painting, writing and guitar are now different skills, instead of the all-encompassing "creativity" skill of The Sims and The Sims 2. Paintings are now more particular to each Sim, based on their traits. Sims can increase their skills by practicing a skill (e.g. playing the guitar, working in the garden, writing a novel, etc.), reading a book about the skill, or taking a class in the skill at a civic building. Sims can begin building their skills as early as their toddler days.While skills do not show up in the meter right away, using skill building objects is rewarded once the toddler grows into a child.

Careers
In The Sims 2, Sims 'disappeared' once they took the carpool to work, and the player had no control of them until they returned, where as in The Sims 3, each career now takes place in a building in the neighborhood that a Sim travels to. New aspects of careers include part-time jobs, overtime, and salary raises. Sims now have a boss to report to. Each career can yield several different rewards and some can be split into several tracks. A new function is that instead of having just skills to advance in a job, Sims also depend on relationships with co-workers and their boss. While at work, the player has a certain level of control over working Sims through 'Options', adjustable settings that dictate how the Sim should go about their work (e.g. take a break, socialize with co-workers, run errands, suck up to boss, etc.), which all come with their set of advantages and disadvantages.

Opportunities
One of the major new additions to gameplay is Opportunities, tasks that Sims can complete to earn rewards. These challenges occur randomly based on aspects of each Sim's lifestyle, such as relationships, skills and job. Career opportunities such as working overtime or completing special tasks can yield a pay raise, cash bonus, or relationship boost. Skill opportunities are requests by neighbors or community members for Sims to solve problems using their acquired skills for cash or relationship rewards.

Create-A-Sim
Create-a-Sim (CAS) is the character (Sim) builder, where the polygon 3-D models of Sims can be modified. New features include the ability to change footwear and headwear separately and add facial details. Sliders have replaced prior functions in CAS. For instance, muscular and obesity sliders replace The Sims 2 system of three body types (Skinny, regular, and overweight). Skin color, voice pitch, and hair color, among other things may also be adjusted on sliders.
The original system of percentage bar personality points has been replaced with a system of traits. These traits include moodlets, interactions, and behavior associated with the trait. For example, a Workaholic Sim is not easily stressed by work and enjoys being at work while a Flirty Sim is more successful with their romantic advances and has more romantic interactions than the average Sim.

Build/Buy modes
The build and buy modes have received their own makeover. The square tile outlines that appeared on the ground in previous Sims games' build and buy modes are now a quarter of their original size to give the player more liberty to place objects where they want. Players can re-color and re-pattern the furniture and other items to specific shades and patterns with the new Create-a-Style and make six story houses with basements.

Create-A-World
On October 29, 2009, Electronic Arts announced "Create-A-World (CAW)", which is a game world editor that allows players to create their own custom cities from scratch for use within the game. The editor tool is offered to players as a separate download (156MB), and was released on December 16, 2009 as a beta version. EA will offer technical support and updates. Players are able to share their neighborhoods as with other content. The Create A World tool is currently only available for Windows based PCs

To date, unlike its counterpart for The Sims 2, The Sims 3 Store only offers exclusive objects, clothing, skins, and hairstyles not found through any other medium.
The store uses a point system in which players can purchase additional SimPoints using a credit card or Points Card, which may be purchased at retail stores. It was launched on June 4, 2009 to coincide with the launch of the game. Players can download purchased items using the game launcher or the Store Mode interface found within the game itself.
