Royal Stone: Hirakareshi Toki no Tobira Game Gear

Royal Stone is a strategy RPG developed and published by Sega for the Game Gear in Japan in February 1995. A sequel to Crystal Warriors, it follows Eva, a former knight of Martalia exiled for apparently turning on her own squad at the front. Battles are played on a grid map with elemental strengths and weaknesses and enemy units that stay unknown until scanned or fought. Unlike Crystal Warriors, it never received a Western release.
