I took the Black Eagles route
I loved the story, the characters, the interactions, the combat.
It was all really good, and a ton of fun.
It took me over 20 hours, and I just started NewGame+ and plan to take the Blue Lions path this time.
Animations are gorgeous, music is phenomenal.
There are some secrets and things that you might find on accident, and some things long-FE fans will see and love and laugh at (i did at least)
