Here's what Nintendo needs to do:
1. Translate and release the first 6 Fire Emblem games and the 12th Fire Emblem game on both 3DS and Wii U Eshops.
2. Path of Radiance HD
3. Radiant Dawn on virtual console.
Alternatively, Nintendo could do this (but it would take a heck of a long time):
1. Take Shadow Dragon, Gaiden, Mystery of the Emblem, and Awakening, put them in one disc, call it "Fire Emblem: Archanea Saga", and release it worldwide.
2. Take Genealogy of the Holy War and Thracia 776, put them in one disc/cartridge, call it "Fire Emblem: Jugdral Saga" and release it worldwide.
3. Take Sword of Flame and The Binding Blade, put them in one disc/cartridge, call it "Fire Emblem: Elibe Saga" and release it worldwide.
4. Take Path of Radiance and Radiant Dawn, put them in one disc, call it "Fire Emblem: Tellius Saga" and release it worldwide.
Regardless of how they do it, it can end up being a very big success for them.
Meanwhile Sacred Stones and the continent of Magvel are forever alone.
