Level-5 revealed the details about Fantasy Life’s DLC: the Origin Island Expansion Pack, where it includes extra content for the game. The game is pricedย at ยฃ7.19 in Europe, therefore it should be aroundย โฌ8.99 for the the rest of continent and $8.99 in North America.
There are still a couple of problems with this: if you buy the Origin Island Expansion Pack, you will be unable to play online with those who did not buy it, making the multiplayer only possible with other DLC owners. In addition, it needs to be purchased in-game after completing the main story.
