This comes from the recent Iwata Asks that we shared...
Iwata: What kind of proposals were you making?
Yamagami: (laughs) A game called Fire Emblem 2011.
Higuchi: Yeah. (laughs) We made proposals that were a complete departure from the medieval worldview so far—like Fire Emblem completely in the modern world or the one which has the sense of an fairy tale. But they were too far out, so we couldn't get started. (laughs)
Iwata: Maeda-san, do you remember what the other suggestions were like?
Maeda: One idea that came up within the team was, well, it was Mars.
Maeda: Yeah. Fighting on Mars.
Iwata: Fighting on Mars?!
Kusakihara: Now I know why Yamagami-san was like, "That's too much!"
Everyone: (laughs loudly)
Now we have some crazy ideas of where the Fire Emblem series might go in the future!
