The Urbz: Sims in the City (handheld)

The Urbz: Sims in the City is the third Sims game and the sequel of The Sims Bustin' Out. This game is loosely-based on The Sims and ported from the GBA version. However, in this branch of the Sims, an Urb (a version of a Sim in the game) lives and works in a city. The game starts out in the largest tower in all of Miniopolis (Kings Tower, which is all of 5 stories) where a Sim is fired, no matter what it does. From there it must find housing, uncover an evil plot, and save the city from falling into the clutches of a crazy egotistical maniac.

Rep Groups
In The Urbz, there are 4 different groups known as "Rep Groups". After the Urb has been designed, the game asks a series of questions, which decide what Rep Group the Urb will belong in. Each group consists of 4 Urbz, excluding the player, has their own Rep Leader, Trophy, Rep Item and Mission. When all 10 bars of the player's Urb are green, the Sim can talk to the Rep Leader and change groups.

The Streeties
 * This group's leader is Darius. If the player answers the first answer for the first quiz question, they will end up as a Streetie. The group's members consist of Darius, Kris Thistle, Ewan Watahamee, and Crystal. The item for the group is the "Ultimate MP-Dee Stereo System" which allows the player to play any music on the game, including the opening theme. Their rival group are the Richies.

The Nerdies
 * This group's leader is Polly Nomial (referring to "polynomial"). If the player answers "Mad l33t computer skillz" for the first quiz question, this is the group they'll end up in. The Group Item is the "Mad Skillz Cerebal Data Infuser", which will raise one skill point a day. The Nerdies of the game are Polly Nomial, Maximillian Moore, Lincoln Broadsheet and Sue Pirnova. They oppose the Artsies.

The Richies
 * Led by Luther L. Bigbucks, his "followers" consist of Misty Waters, Lily Gates, and Lottie Cash. If the player chooses the 3rd Option on the First Question, money, this is the group they'll end up in and will also end up with the group's item, a "Sensory Deprivation Chamber", which fills up all motives. Their rivals are the Streeties.

The Artsies
 * The Artsy leader is the Carnie, Roxanna Moxie. If the final option of the first quiz question is filled, the Urb will belong in this group with Roxanna Moxie, Cannonball Coleman, Pritchard Locksley and Theresa Bullhorn. The Urb will also end up with a "Bod Mod Changer" which allows the player to change their Sim's skin and hair color. Their rivals are the Nerdies.

Though the Rep Groups are one of the game's main focuses; Bayou Boo, Berkeley Clodd, Busta Cruz, Crawdad Clem, Cynthia Braintrust, Daddy Bigbucks, Detective Dan D. Mann, Dusty Hogg, Dr. Mauricio Keyes, Erphram Earl, Futo Maki, Gary Geezer, Giuseppi Mezzoalto, Gramma Hattie, Harlan King, Jack I. Deal, Mamba Loa, Olde Salty, Phoebe Twiddle and Sharona Faster do not belong to any rep group.

Xizzles
Xizzles are mini-skills. Xizzles can be bought with 3 Xizzle Beads, which can be obtained by talking to Urbz and getting their Rel. Points to 75 or above, or finding them around Miniopolis, where you can buy 1 Xizzle. A Xizzle can be like "Livin' Large" which earns you 20% more at Jobs/Minigames, or they could be like "Nemesis", of which everyone's relationship points will go up 6 but someone else's down to minus 100. In the CAS Quiz, all questions except for the first determine which Xizzles will be available first to your Sim. Other Xizzles can be obtained after completing Goal 2 in Mission 3 (Daddy Bigbucks & The Xizzle Factory).

GBA and DS differences
This is the differences between the GBA and DS versions Some Xizzles might be in a different place then it was in the GBA version (For example: In Water's Gym the Xizzle was found in the plants in the GBA version and in the DS version the Xizzle is found in the locker) Urbz might be in a different area then they were in the GBA version (For expample: In the GBA version at 6:00 PM Sue Pirnova is in the Miniopolis University and in the DS version at 6:00 PM Sue Pirnova might be at Splicer Island instead.
