Moon Dragon is an RPG in Japanese. The main characters Rune (ルーン) and Blair (ブレア) are searching for their missing father. Arriving in Kukuru village, the locals tell them about a terrible monster called the Dragoyle, which was magically sealed away for a long time, but managed to break free.
The game features first person dungeon crawling, which proceeds mostly on rails with pre-rendered CGI videos, only taking decisions from the player when the path is branching. Battles follow the Active Time Battle system. Other than the dungeon crawling, the game does not feature many animations; enemies and NPCs are still images, sometimes with effects applied to them. Dialogues feature full voice acting, but no subtitles.
