This spring in Japan the swords, axes, and spears of Fire Emblem spring forth from the 3DS screen to pierce your eyeballs with varying degrees of severity depending on which sort of weapon you're holding at the time. Check out the live stream of the game from the Nintendo Direct presser.
One of the first 3DS games to support downloadable content looks like it's coming with a pleasing combination of 2D travel and 3D battles packed right in. Will it be formulaic? Dude, Fire Emblem is the very definition of formulaic. It wouldn't be Fire Emblem otherwise.
It's the same old game with a few new lines of code and sharp visuals. Sometimes that's all you really need.
