Each skill has a tab in the skill journal detailing the level of the skill, statistics, what the challenges are, and sometimes other special information.
If importance cannot be established, the section is likely to be moved to another article, pseudo-redirected, or removed.
The game play is open-ended and does not have a defined goal.
Challenges occur randomly based on aspects of each Sim's lifestyle, such as relationships, skills and job.
There are several skill-dependent abilities, such as more social interactions available from high charisma, special songs for guitar players, and appliance upgrades (self-cleaning, more TV channels, etc.) for high handiness.
Sims can begin building skills as early as their toddler days.
The player has a larger selection of body types for Sims as muscle and body weight sliders have been introduced.
