Mother 3 is a role-playing video game for the Game Boy Advance handheld game console, developed by HAL Laboratory and Brownie Brown, published by Nintendo. It is the third video game in the Mother series of video games. It was announced in June 2003 during a Mother 1 + 2 television commercial, though details of its development were kept secret. Up until its release, the game remained near the top of Famitsu's most wanted games list. Immediately before its release, Mother 3 was the most wanted game in Japan according to Weekly Famitsu.
According to Shigesato Itoi, the lead designer of the Mother series, there are no plans to create a Mother 4.
Mother 3 starts out very differently from the first two Mother games. The game is set up into eight different chapters, much like Dragon Quest IV. Instead of focusing on a group of children, it chronicles the story and adventures of Lucas and his family, and the story switches perspective during each chapter. (For example, the first portion of the game are led by Flint, Duster and Salsa (for the first, second and third chapters, respectively), but the rest of the game is led by Lucas.) Nowhere Island also changes dramatically due to the influence of the Pig Mask Army, transforming from a simple low-tech rural society to a more modern 21st Century infrastructure that's similar to the first two Mother games (hence the game's theme of nature vs. technology). The game also features a more traditional top-down RPG perspective, instead of the oblique projection used in the first two games.
