Fire Emblem is an old series of strategy RPGs going back to 1990. Shining Force borrowed a lot of elements from FE, but theres one very big difference. In Fire Emblem if a character falls in battle, they die permanently. (note: newer games have a casual mode where fallen allies come back next chapter)
At the time of writing this there are 10 games and 2 remakes as well as a rumor floating around about 2 games on the 3DS.
(Note: Rekka no Ken/Blazing Sword is the 7th game in the series and the first to be released in the US, its just called Fire Emblem in the west.)

EDIT: thanks for moving this to Nintendo, blu, I kinda got excited and posted it in general because of the new games.
