Ornic Senki is a remake of First Queen. The game retains the basic gameplay and the story of the original. Some scenes and dialogues were added (for example, the intro features a detailed account of what happened in different kingdoms after the Ornic invasion, which was absent in the original version). The battle system remains the same, but the player has more options to customize the party AI. Also, instead of choosing locations from a menu and being able to view the world map only before major battles, the player is actually navigating the world map now, physically moving to the dots that represent locations.
The remake features new musical compositions and sound effects, as well as more detailed 16-bit graphics.
