Okay, so basically, the reason I’m asking this is because I have never played the series, apart from Fire Emblem Heroes, and a demo for Fire Emblem Awakening. So, I don’t know much about it, tbh. I’ve been wondering which game to start with, but I’m worried that all the games are connected with one big story. So, would you guys mind helping me out here and recommending which game I should start with first?
Don't worry about starting with the "wrong" one, storywise most of them aren't in the same universe
I wouldn't recommend to start with the 3DS Fire Emblem games; Awakening's map design is pretty bad and the story is lackluster at best. Fates: Conquest has a much worse story but much better gameplay. Fire Emblem Echoes: SoV has a great story, characters and presentation, but maps are plain at best and dreadful at worst.
Fates: Brithright and Fates: Revelations fail at every possible level
If you have a Wii U, I would really recommend to get both GBA games avaliable. The Blazing Sword (Just called Fire Emblem in the west) is easily the best to start with. It has a very good difficulty curve, and a 10 chapters prologue specifically made for to introduce those who never played a Fire Emblem game. It also has a great story, that starts off simple but it unveils as you progress through the game.
Sacred Stones is the other FE GBA game in the Wii U. Is also a game recommended to start with, tho I would advise to never touch the Tower of Ivaldi until you beat the final boss. The game is already pretty easy and grinding just makes it boring
The Tellius games (aka FE 9 + FE 10, aka Ike's games) are my favorites, but they introduce a bunch of mechanics that could get overwhelming to those just starting with the series
As a last few tips:
- Never play in Casual Mode. The whole point of the series was to make every character feel important, to teach the character to be mindful andcareful with the lives of their units, and every map is designed with the permadeath system in mind. Making you fallen units come back after dying hurts the game's difficulty to the point that it destroys any meaningful strategy the palyer can come up with. If you want the game to go easy on you, just play on easy mode.
tl;dr Only ever play classic mode
As a second tip, watch Mekkkah's Fire Emblem pitfall series on Youtube. They are great starter guides that will help you out no to fall into noob traps
