Miniopolis

Miniopolis  is one of the major cities in SimNation. It is the location of The Urbz: Sims in the City for the Nintendo's Gameboy Advance and Nintendo DS handheld consoles. This city is mentioned in The Sims 2 for Game Boy Advance. Its name could be a parody of Minneapolis, Minnesota. The city is also likely based off of New Orleans.

The main antagonist is named Daddy Bigbucks. He buys King Tower in Glasstown and plans to demolish Miniopolis, then rebuild it with ticket booths, taxes, and more materialistic ideas.

Glasstown
This is where the player starts out (inside King Tower to be specific). It is the tutorial area and other areas are not accessible until completed. The player's Urb gets arrested here and sent to Urbania Jail. It gets re-opened later in the game. It contains the Carnival, Cinema d'Urbania, Glasstown Mega-Mall, an entrance to Club Xizzle, Rep Group Clubhouses, the Coffee Shop, a city apartment, and King Tower, which in and of itself contains Lily Gates' Office, Waters Gym, Daddy Bigbucks' office, and a penthouse. The player can play miscellaneous carnie games as the carnival and Squeegee Clean at the top of King Tower.

Urbania
Urbania is the 1st area (after tutorial) to be unlocked, it looks like a more rundown area and it is where the player meets many new Urbz. It contains the Jail, Miniopolis Chronicle, Miniopolis Hospital, an entrance to Club Xizzle, Second Looks Thrift Emporium (Phoebe Twiddle's shop), a Junked Schoolbus (that the player can get access to by maxing out friendship with Giuseppi Mezzoalto), Slice O' Life Pizza, two houses that the player can purchase, and a Workshop. There are also four minigames in this area, Hoopz (top of the police station), Doctor Max Stat! (Miniopolis Hospital), Comic Explosion (Slice O' Life Pizza), and Motocross Mayhem (the workshop).

Sim Quarter
Sim Quarter the 2nd area to be unlocked, the Sim Quarter is a farmer's market/pier. At the end of the last goal of the Sim Quarter, Daddy Bigbucks tosses the player's Urb into the water. This area contains Salty's Riverboat, the Graveyard, Crawfish Shack, Epoch Museum, Fortune Teller's Shop (ran by Mambo Loa), Sim Quarter Farmer's Market, Zeke's Zydeco Club, Café Multiplaya, and a townhouse that the player can purchase. The player can play Moogoo Monkey in Salty's Riverboat and Yar Hey! Bombard! on the docks.

Bayou
The player's Urb wakes up here after being tossed into the water, and all the missions are about escaping and helping out the two residents, Bayou Boo and Crawdad Clem. There is not much in the area other than the Twins' Bayou Shack. The player can play a minigame called "Soul Music" with the Red Man in this area as well.

Paradise Island
Paradise Island is a small island with a beach. It has a small store which sells tiki themed items, and a hammock for the Urb to sleep on. During a mission, the player will play a reality TV show on it.

Splicer Island
Splicer Island is only included in the DS version. After 10 days, Futo Maki has used the monkeys in the ruins and worked on it. Splicer Island will be rebuilt and now the player can do all of the good stuff which includes gene splicing and pet contests.
