I translated the entire Famitsu review for Fire Emblem Echoes: Shadows of Valenta (Echoes: Another Hero King in Japan). It received an overall 37/40 rating from four reviewers. The break down was 9/9/10/9. I post a translated image, but the transcript can be found after for reference. It is from the April 13 2017 issue of Famitsu.
A big thank you to VincentASM of serenesforest for providing the review scan! Look forward to serenesforest’s own view on the review and other info gained before the game releases next week.
