(Note: The next section is an introduction to the series for those who are unfamiliar with it. If you already know how the series plays, feel free to skip ahead to hear about this game in more detail.)
One thing to note is that the game ends on a cliffhanger of sorts. The problem with this is that the story is actually continued by the previous game, Fire Emblem 6, which was never released outside of Japan. You can find fan translations of the game online, but it's still disappointing we never got the full narrative in the west.
As far as the audio and visual presentation go, it's pretty good for the Gameboy Advance. The graphics aren't pushing the system's capabilities, but the spritework is excellent and the environments are nice to look at. I really like the way each class has its own unique sprite, and the amount of detail in the battle animations is particularly impressive. The soundtrack is also solid, with some great compositions. While it may not be very memorable, the music is enjoyable and helps create emotion. You may not buy Fire Emblem because of the way it looks and sounds, but it still has a great presentation considering the system's limitations.
