This game was my first foray into the fire emblem world, many years ago. And might I say, what a game it was!
For anyone that enjoys turn based combat (with JRPG style battle screens whenever you encounter the enemy) I can’t recommend this game enough
Every unit you take onto the battlefield is a a unique character with their own backstory, playstyle, strengths and weaknesses
And each unit is upgradable, based on the amount of combat they’re involved in. I remember multiple plays through where I would (for example)p only use knights, and level up a massive army of cavalry, or focus on mages to have a squad of spell casters
One thing unique at the time (as far as I can remember anyway) was that the game fetuses permadeath, where losing a character in battle ment they wouldn’t be with you to the end.
Similar to games like Xcom, this made you really focus on strategy and doing the best you could to try and teach the finale with your entire army intact
Another unique feature was story based encounters, where you had the potential to make new allies, recruit enemy soldiers, etc, depending on which characters you chose to use on a specific enemy.
All of that works together to make every encounter feel unique and interesting, with a ton of strategy and ways to play.
In short, this game was a masterclass in turn based combat, which brings something for everyone to enjoy, weather you have 5 minutes or more hours. I’d highly recommend.
