Dragon Warrior II, known as Dragon Quest II: Akuryou no Kamigami (ドラゴンクエストII 悪霊の神々?, lit. "Dragon Quest II: Gods of the Evil Spirits") in Japan, is a role-playing video game (RPG) developed by Chunsoft and published by Enix (now known as Square Enix) in 1987 for the Nintendo Entertainment System as a part of the Dragon Quest series. Enix themselves created the American version of Dragon Quest II, publishing the game there in 1990.[3] Dragon Quest II is set 100 years after the events of the first game. The game's story centers on the prince of Midenhall, who is ordered to stop an evil wizard named Hargon after Hargon destroys Moonbrooke Castle. On his adventure, he is accompanied by his two cousins; the prince of Cannock and the princess of Moonbrooke. Dragon Quest II greatly expands on the series formula from the first game by having a larger party, more areas to explore, multiple heroes and enemies in a battle, and a sailing ship. Dragon Warrior II was successful in Japan; the original Famicom version shipped 2.4 million copies. Later, the game was remade for the Super Famicom and the Game Boy Color with Dragon Warrior as Dragon Quest I & II. A version of the game for Android and iOS has been announced for release in Japan in Winter 2014.[2] The third title in the series, Dragon Quest III: And Into the Legend..., was released in 1988 in Japan.[4] Dragon Warrior III is the prequel of the first two games; it follows the ancestor of the main characters, the legendary hero Erdrick;[5] the three games are collectively called "Erdrick's Legend Trilogy".
