The game features a party-based combat system with a turn-based structure and elements of sci-fi.  It expanded upon the original Phantasy Star by adding new features including a more expansive world map and improved RPG elements.

Phantasy Star II was developed by Sega and is considered a landmark title in the RPG genre for its time, influencing many games to come.
