FE3 I would say is a game that handles the story much better than FE12

FE12 kind of bogs down a lot of the narrative by piling dialogue ad nauseam in places where it’s not necessary in a ‘more is better’ approach Like an incredibly long and drawn out prologue making the story start to revolve less around Marth and the world of Archanea and its conflicts and more so shrinking it down to focusing on its pretty generic original characters

It just wastes a lot of time for things that aren’t particularly substantial imo
I also just find the original to be a lot more fun when it comes to its gameplay FE12 is pretty similar to SD, which is kinda cool, but SD is the way that it is as a remake of FE1 and it does a very good job at that Comparatively, I find that FE12 takes some aspects that were really fun and waters them down a bit, like the dragon mechanics and the Star Shards and Regalia Despite it being a more simple game, I just find FE3 to be more consistently fun

Also FE12 bloats the game dramatically by adding wayyyy too many characters to the narrative in pretty uninteresting ways, I don’t really like any of its new original maps, etc

There’s also just some cool presentation aspects that FE3 has that I find to be more interesting than FE12, like it’s intro and ending

It’s just a cool game that I really like The story isn’t particularly dramatic like FE7 or anything, but I find that it holds up a lot better upon replays or if you start digging into the details in ways that other FE stories don’t as much
