Natsume recently announced that Harvest Moon: The Lost Valley is coming to 3DS in 2014, and has today used its pre-E3 press release to confirm two more titles coming to Nintendo systems; both seem like candidates for the eShop, though that's not confirmed.
First up we have A-Train: City Simulator on 3DS, a long running series in Japan. It promises to blend city and transportation simulation, as you're the head of the local transportation agency — your job is to keep trains, buses and subway services running smoothly.
Next we have Alphadia Genesis, an RPG that can be found on smart device platforms and Natsume's first planned release on Wii U. Developed by Kemco, this appears to feature turn-based battles, 3D visuals and a typically epic storyline.
Finally, there's an updated description for Harvest Moon: The Lost Valley, which gives a little more context on the storyline — you can see this below.
Hiking your way through the mountains one day, you become caught in an unexpected snowstorm, and find shelter with the help of a faint voice. When you awaken, you find and help a kindly Harvest Sprite buried under the snow, who tells you all of the seasons in the valley have vanished except for winter. To return all 4 seasons to the valley, you'll need the help of the villagers, the Harvest Sprites, the Harvest Goddess, and even the King of the Underworld!
So there you have it. Which of these Natsume releases are you keen on?
