Fire Emblem: Genealogy of the Holy War

Has a really unique approach to FE in that the maps feel like they're all one big battlefield rather than a bunch of smaller, separate maps focused on a gimmick. It actually feels like a full on conflict, which is complemented by how much darker the plot is in contrast to the rest of the series. That said, the big maps have less variety than future games and it also has a lot of archaic features like its support system. I think the game is a bit overrated, but it's still a damn good time.
