Imagine my disappointment when I found out that this is essentially nothing more than a handheld adaptation of the latest Phantasy Star Universe game, Ambition of the Illuminus. Essentially, here's how it works. You start off by creating a generic character for yourself, choosing to create either a male or female character from one of four races, tweaking his/her physical appearance and ultimately choosing from one of several classes. The detail in the character creation system is impressive, as you can even alter the pitch and tone of the character's voice. After that, you can choose to play alone in Story Mode or join up wirelessly with a party in Multi Mode.
Either way, you're in for action-based combat and gameplay that focuses on completing missions, somewhat similar in nature to Final Fantasy VII: Crisis Core. The nub is used to control movement, while the square button is used for a normal attack and the triangle executes a special attack. You can set different weapons and items to a special menu, mapped to the circle button, that makes healing or switching equipment a snap. The X button is used to pick up items or investigate, and the L button can alternatedly be used to lock-on (when facing an enemy) or strafing (when running). Truth be told, the combat is my favorite part of Phantasy Star Portable.
