Rune Factory 4.
Rune Factory 4 (ルーンファクトリー4, Rūn Fakutorī 4) is a simulation/role-playing game developed by Neverland Co. and published by Marvelous AQL for the Nintendo 3DS. It is the sixth game in the series and is also the first to be released on the 3DS. The game was released in Japan on July 19, 2012 and in North America on October 1, 2013. The game's release in Europe was canceled due to the bankruptcy of Neverland, but XSEED Games later published the game in Australia and Europe, making it available to download on the Nintendo eShop on December 11, 2014.
The story of Rune Factory 4 begins upon an airship headed for Selphia. Lest or Frey (depending on which option you choose) has something important to give to Ventuswill. Soon after they are ambushed by two soldiers who were hiding in barrels. Although the soldiers are quickly defeated Lest or Frey is soon caught off guard and knocked out, resulting in the stones they were carrying to be thrown off the airship and causing them to lose their memory. Thinking the memory loss to be a joke they are threatened to get thrown off the airship, only to actually get thrown off by accident. Falling from the sky they land on top of a dragon; it is Ventuswill. Mistaking them for the "prince" they were expecting from the capital they are made the Prince/Princess of Selphia and are made to live in the castle.
However, the next day it is discovered that Lest or Frey is in fact not the prince/princess whom they were expecting when the real prince, Arthur D. Lawrence, the 13th Prince of Norad, arrives. Ventuswill is embarrassed by this fact as they had given away the room that was meant for him. Although Arthur is a bit surprised by this he offers his job as a prince to Lest or Frey and teaches them all the responsibilities that come with having such a title.
Your job as the Prince/Princess is to farm the land and help the citizens of Selphia, but there is more to the game than that. You will farm crops, do orders to expand your farm or develop Selphia, befriend monsters, make friends with the people, craft weapons and armor, venture into dungeons, get married, and so much more. It is absolutely amazing and I love it so much.
