Review taken from GameSpot.com
Xenosaga Episode III is a fitting, if convoluted, end to the cinematic science-fiction role-playing trilogy.
The Good: Intuitive battle system and well-balanced customization; great in-battle graphical effects; characters are all given a fitting sendoff.
The Bad: Story is wrapped up well, but you’ll need to constantly reference a database to keep up with it; obviously edited blood makes a number of scenes completely absurd.
Monolith Soft’s Xenosaga series is noted not only for its wordy German subtitles and lengthy cutscene exposition, but for its hugely complex storyline that’s influenced by equal parts science fiction, religion, and myth. The series’ first two chapters ended with far more questions and mysteries than they answered or explained, so Xenosaga Episode III: Also Sprach Zarathustra begins with an almost ludicrous amount of enigmas that need resolving. Fortunately, Xenosaga Episode III manages to wrap things up in dramatic and mostly satisfying fashion for the memorable main cast and the universe that they inhabit, while simultaneously leaving the door open for a continuation.
