Personally, I love it. The gameplay is a little different from standard Warriors games: there's still a lot of hack 'n slash going on, but there's also a lot of strategy involved; it actually feels like a Fire Emblem game, and I was genuinely challenged despite being a Warriors veteran.
Xander and Cordelia are probably my favorite characters to use, due to their fast movement and great crowd-clearing abilities. I also really, REALLY like Lissa's moveset. (Actually, I have relatively few complaints about the roster in general; SD/Awakening/Fates might not be my favorite FE games, but I like the way they were represented here for the most part.) I just hope they make Validar and Iago playable in a future update.
Really, my only complaint about the game is Rowan's characterization. He was fine gamplay-wise, but I found his personality on the annoying side.
So, has anyone else here played this game yet? Love it or hate it? Discuss!
