Free will

Free Will enables the Sims to move without your direction. They can move and do certain actions without you telling them to, if you turn it on in the menu. Most of these actions are in connection with their needs, they do others just for fun. Free Will is on every game and can be enabled or disable but two exceptions are to this is The Urbz: Sims in the City and The Sims 2 Castaway

Free Will is set for each lot and can be set from the "Game Options" menu. When a family moves into a new lot, they will have Free Will on.

Certain things like WooHoo will not be done by Sims with this turned on. You will need to direct them.

Some things that Sims do in Free Will won't occur when Sims are in a very bad mood.

The Sims
Free Will can be enabled or disabled, Disabling Free Will does not have Sims do anything. Free Will is enabled by default.

The Sims (Console) and The Sims Bustin Out
Free Will is similar to The Sims and the same thing applies to The Sims as well

The Sims 2
Like The Sims, The Sims 2 can have Free Will enabled for disabled. Free Will is more advanced and better than The Sims Free Will.

The Urbz: Sims in the City
The Urbz: Sims in the City does not have a Free Will option and Free Will cannot be disabled, The Sims 2 restored this option and allows the user to disable Free Will.

The Sims 2 (Console)
Free Will is restored that was removed from The Urbz: Sims in the City. Free Will is pretty much similar to The Urbz and earlier games. (As Sims do the same function as the Urbz did in The Urbz: Sims in the City)

The Sims 2 Pets (Console)
Free Will is similar and behaves like The Sims 2. However it has a Timer when to enable Free Will. ex. 2 Min

The Sims Stories series
Free Will in The Sims Stories is similar and has the same features like The Sims 2.

Note: The Sims Castaway Stories can have Free Will disabled unlike The Sims 2 Castaway in which Free Will cannot be disabled and only allows the user to set the Time

The Sims 2 Castaway
The Sims 2: Castaway does not allow the users to disable Free Will (unlike it predecessors The Sims 2 Pets and The Sims 2) but can be configered.
