Dragon Quest I and II are the first two parts of the first Dragon Quest trilogy. Dragon Quest takes place in the kingdom of Alefgard, where you play as the descendent of the great hero, Erdrick. The evil Dragonlord is causing havoc, while at the same time, a dragon kidnaps Princess Gwaelin. In a solo journey, the hero travels throughout Alefgard collecting key items to reach the castle of the Dragonlord, and saving the kingdom.
Dragon Quest II happens 100 years after the first Dragon Quest game. The descendent of the hero from Dragon Quest reside in three kingdoms, eventually joining together to battle the wizard Hargon. The world of Dragon Quest II is far larger than Dragon Quest, and Alefgard makes up only a small part of the map. Due to this, travel gates and a boat allow the heroes to travel the overworld.
Dragon Quest III
Dragon Quest III is noted for greatly expanding upon the gameplay of the original Dragon Quest and Dragon Quest II.
Dragon Quest III is set many years before the original Dragon Warrior in a world separate from the first two games. A wicked fiend named Baramos threatens to destroy the world. The story revolves around the Hero, son or daughter (the player can choose to be either male or female, with few gameplay changes) of the legendary warrior Ortega. On their sixteenth birthday, the Hero is summoned to the castle and is given by the King of Aliahan the challenge to rid the world of the evil archfiend Baramos, which Ortega attempted in the past but seemingly perished in a volcano. The Hero then is able to recruit up to three traveling companions to help fight Baramos.
Dragon Quest V
Dragon Quest VI
Dragon Quest VI: Realms of Revelation is a role-playing video game developed by Heartbeat and published by Enix for the Super Famicom as a part of the Dragon Quest series and as the last Dragon Quest game in the Zenithia trilogy.
Dragon Quest VI sold over three million copies in Japan, becoming the best selling game of 1995.
The story follows the traditional Dragon Quest "Hero" on a quest to save the world. In this particular installment, the heroes also have to endure the personal struggle of amnesia, as many of the main characters do not initially remember who they are.
