Emerald Dragon

The game utilizes a top-down overhead perspective, in which players move the controllable character in two dimensions. As players navigate the world map, they may encounter battles that are turn-based and employ a time point system: both movement and attacks deplete a bar displayed at the top of the screen, and a character's turn ends when this bar is exhausted. Experience points, used to level up playable characters, are earned by defeating enemies.

Stronger attacks for the main protagonist, Atorushan, become available through the collection of key items called Emerald Graces. These items allow him to transform into a dragon to unleash a powerful attack, at the cost of reducing his HP when used.

A long time ago, dragons and humans lived in peace in the land of Ishbahn. Lord Tiridates, believing that the presence of dragons among humans defiles Ishbahn, casts a curse that kills dragons in the region. Some of the dragons—now collectively known as the Dragon Tribe—manage to escape and find refuge in Draguria, where a dimensional rift prevents humans from crossing.

At the start of the game, a ship wrecks on the coast of Draguria. The protagonist, a Dragon Tribe youth named Atorushan, seeks the friendship of the sole survivor, a human girl named Tamryn, under the guidance of the White Dragon, leader of the tribe. The girl is cared for by the dragons of the land, but twelve years later, she departs in search of happiness among her own kind. Atorushan breaks off his left horn and gives it to her as a means of summoning him should she ever require help.

Akihiro Kimura successfully crowdfunded a sequel audio series titled Elemental Dragoon in 2015. It is based on ideas that were proposed for a sequel to Emerald Dragon in the 1990s but never came to fruition due to apparent copyright issues. Despite this, Kimura and others created several independent dōjinshi and novels that continued the story over the years, as well as creating a video game adaptation of his audio series titled Elemental Dragoon: Futatsu no Hikari. The series was designed to circumvent copyright issues by focusing on new characters and slightly altering names, including the title, although the original characters appear at the end. It was also intended to help Kimura generate interest in a true sequel to Emerald Dragon and potentially regain the copyright.
