*claps hands and rubs them together* Hooo boy, here we go.
With regards to Fates narrative, do I think it could do better? Sure. It's at least better than Awakenings so that's a baby step in the right direction.
The Stork has more plot relevance than the Fates kids do. I'm fine with the next generation just don't pop out of nowhere and shout surprise.
Does Fire Emblem have an identity crisis... I wouldn't go that far. IS is just sticking with what works, if it isn't broken, don't fix it. I don't blame them for that either considering the fact that if you all recall pre Awakenings sales, Fire Emblem was in a bit of a free fall what with Shadow Dragon selling poorly and New Mystery being Japan exclusive outside of emulating it. Awakening was to be the last in the series. Nobody thought it would sell so well so I think that after such a commercial success after a few years of less than desirable sales, IS decided to mix it up and try something new. Fates tried to mesh together old and new and you get an ambitious game trying to make everyone happy and when it all comes right down to it, be it story or gameplay, I think we all have our likes and dislikes about it but it's still, at its core, an enjoyable experience no matter how you slice it.
My opinion on "Waifu Emblem". I don't mind it. I'm all for personal opinions but once you start stating your fan fic as fact, you bet your Faceless behind I'm gonna proc Curse Reflection.
Gender locking classes and weapons was ok but now I don't really see the need to anymore what with hardware limitations being far better than they once were. Just don't alienate people by giving one gender a really cool class and the other marriage as a literal class. C'mon devs.
