Fire Emblem: Awakening project manager Higuchi was playing with ideas to expand the Fire Emblem audience. While he settled on a traditional fantasy setting for the Nintendo 3DS game, Higuchi had other ideas which he revealed in an Iwata Asks interview.
One of his unrealized ideas was Fire Emblem 2011, a Fire Emblem style game set in modern times instead of the usual medieval setting. Another team member had the idea of making a Fire Emblem game where you fought on Mars.
Neither title was realized, but what do you think of the suggestions. Modern Fire Emblem kind of sounds like Advance Wars, but a Fire Emblem game on the red planet with sci-fi elements… that could be interesting.
