I didn't find Awakening's story to be bad, just really simple. The themes of this game are already a lot more intriguing, and as I said, the whole story isn't even out yet.
Though it's obvious that the main focus of the 3DS games are the chararacters themselves, which is fine with me too.
Yeah, I put around 100hours into FE:A and barely remember next to nothing storywise. It was fun building characters but the story was bland as fuck. I just grinded the hell out of my characters so I could beat that last DLC story.
Hmmmm... let's see...
Bad guys come to revive dragon god. Chrome is heir to special sword who must stop the revival. Sister kills herself for some reason. Everyone gets beat up. Future Girl Marth and Friends join the battle. Stones pop up for no apparent reason and are all giving to you. Get new shiny Sword. Kill Bad Guys and Dragon. The End.
