Fire Emblem is a fantasy tactical role-playing video game franchise. Many games in the series have sold well, despite a decline during the 2000s which resulted in the series' near-cancellation. Individual entries have generally been praised, and the series as a whole has been lauded for its gameplay, and it is cited as a seminal series in the tactical role-playing genre. Characters from multiple games have also been included in crossovers with other franchises.
A recurring element in the series is the titular magical Fire Emblem. Its name derives from its connection to dragons and weapons of war, being the "emblem of flame". Other magical elements, including feuding gods and mystical species such as dragons and shapeshifters, are also recurring elements in the series. The Fire Emblem games take place across multiple unrelated settings within a Medieval or Renaissance-themed time period, with the main protagonist, usually royalty, caught in the conflict of two or more countries across a continent and fighting for their cause. The gameplay revolves around tactical movement of characters across grid-based environments, while incorporating a story and characters similar to traditional role-playing video games. A noted aspect of gameplay is the permanent death of characters in battle, removing them from the rest of the game should they be defeated. In the newer titles, from "New Mystery of the Emblem" onwards, players get the choice between Classic mode, where characters permanently die, or Casual mode, where fallen characters revive for the next battle. Both inside and outside battle, character relationships can be developed, increasing certain battle abilities. A feature introduced in Genealogy of the Holy War and used in later titles was characters who fall in love can have a child who inherits certain skills and stats from them.
