Unironically hope you have fun with it. It's a really fun game to play once you're familiar enough with its mechanics, and it introduced my favorite iteration of weapon forging. Basically as long as you forge the Wing Spear and Ridersbanes with high might you basically can't lose. And the localization has my favorite depiction of Marth in the entire series, he's a sassy little shit in this one.
Once you're more familiar with how Fire Emblem plays, I highly recommend that you try Genealogy of the Holy War, it's one of my favorite games of all time.
A lot if the people on the Switch board said the DS version was garbage so I'm hoping your recommendation is closer to reality. ---
