Crystals of Arborea is an RPG which is a precursor to the Ishar games. The party of six characters roam the world (on a 2D map or by exploring 3D individual locations), defeating Mogroth’s minions, gathering experience points and becoming stronger. Unlike the subsequent Ishar games, combat in this game is turn-based, and takes place on separate screens. The players must manually navigate party members on the battle field. Archers and spellcasters can use ranged attacks, while melee fighters must stand close to the enemy in order to strike.
