I've actually almost finished this game twice, and both times I lost my cartridge or had to give it away (long story). It's the second GBA Fire Emblem game (the Japanese subtitle translates to "Sword of Raging Fire"), though the first one to be localized by Nintendo, and the first in the series to make it to the West. Given how well it has sold I bet they are feeling like idiots for not bringing over all the previous games.
Post impressions here. I'll try to finally finish it this time, though I'll be taking it slow because at the same time I am also playing Seima no Kouseki, the next game in the series.
