Environment

Room (The Sims and console games of The Sims 2 and The Sims 2 Pets) and Environment (The Sims 2 and The Sims Stories) are needs. Although this need is not in The Sims 3 and The Sims Medieval, object catalogs still mention Environment.

The Room/Environment meter is often overlooked, and is a combined rating that analyzes the design and content of the room that the Sim is currently standing in. Different factors can affect this motive; for example, Sims don't like small rooms, or rooms with not enough light or windows, nor do they like dead fish in the aquarium, dead plants, walls with no texture on them, foundations will no floor texture on them, dirty plates, puddles or ash piles, or dirty or broken objects. Certain purchases will improve the room rating, such as expensive fireplaces, sculptures, landscaping, or paintings.

The Sims and The Sims Bustin' Out
This meter is known as Room in The Sims, and both child and adult Sims have it. If Unleashed is installed, pets also have it.

The Urbz: Sims in the City
Room is not present in The Urbz: Sims in the City, but some objects have stats for Room.

The Sims 2 and The Sims Stories
In The Sims 2, it is renamed Environment, and does not appear until a Sim becomes a teen. In The Sims 2: Pets, Environment is replaced with Scratch (for cats) and Chew (for dogs).

An alarm clock waking a Sim will make their environment bar completely red, until they turn it off. If they can't, their mood will drastically decrease, but it quickly recovers once they finally turn it off. An accident or fire causing Sims to panic will also drain all of their environment bar.

If there are too many plates of spoiled food around a Sim, and a Sim's environment bar is low, he or she may die by flies.

The Sims 2 console games
In The Sims 2 and The Sims 2 Pets, the motive is Room, which is same as The Urbz: Sims in the City. However, in The Sims 2 Castaway, the motive is Environment.

The Sims 3 and The Sims Medieval
The Environment need has been removed in The Sims 3 and The Sims Medieval.

In The Sims 3, the environment bar has been replaced by moodlets.
