Short answers, pulled from the story.
Final Fantasy Tactics Advance is a 2003 tactical role-playing game developed by Square for the Game Boy Advance. It was published by Square in Japan on the 14th of February 2003 and by Nintendo in Western markets later that year. It is a successor to Final Fantasy Tactics from 1997.
By November 2003, Tactics Advance had shipped over 1.5 million copies worldwide, with 460,000 units in Japan, 760,000 in North America, and 330,000 in Europe. A separate estimate placed United States sales at 660,000 copies and $22 million in earnings by August 2006.
Square developed Tactics Advance, with Yasumi Matsuno as producer, Yuichi Murasawa as director, Satomi Hongo as lead designer, and Shinichi Fujisawa as lead programmer. Hitoshi Sakimoto composed most of the music, and Nobuo Uematsu wrote the main theme.
The Law system places restrictions on available actions during battles, such as banning certain spells, items, or weapon types. Neutral Judges enforce these rules; a yellow card lowers hit chance, while a red card removes the offending unit from the battlefield. Later in the game, players can use Law cards to set or erase Laws.
The project was initially considered for the PlayStation 2 but shifted to the Game Boy Advance due to a combination of public demand, Square's reconciliation with Nintendo after years of estrangement, and the joining of former Quest Corporation staff to Square's development team.
Tactics Advance won the Handheld Game of the Year award at the 7th Annual Interactive Achievement Awards in 2004. It was also nominated for Strategy Game of the Year at the 2003 NAVGTR Awards. The game earned aggregate scores of over 88% on GameRankings and 87 out of 100 on Metacritic.
