Some of the new features of the game include: diving, community projects, more mini games, more ways to play using Wi-Fi and more shops. The community projects are where you're able to build your own benches, lampposts, fountains and rose arches like the one above.
Japan and Korea are currently busy playing the game and New Leaf became the first 3DS game to pass two million units sold. Currently, the game has sold nearly three million copies so it's a big hit! The game will be released in Europe on June 14th and in America on June 9th so there's still a bit of waiting time yet.
