9.0 Presentation
Improved load times, an absolutely enthralling storyline, a powerful ending, and easy-to-access menus give Episode III the best production values in the series.

7.5 Graphics
There is definite slowdown during cutscenes and character animation is on the stiff side, but the keen artistic design, cool facial expressions, and expansive environments shouldn't be overlooked.

8.0 Sound
While not as good as Episode I's musical score and strangely downgraded to stereo from 5.1, the soundtrack and voice acting in Episode III are both of a high level. Audio effects are solid.

7.5 Gameplay
A tweaked combination of Episode I and II's battle systems works well with a nice variation of tactics and fun ES combat (but there's nothing original here). Some boss battles can last an hour.

7.0 Lasting Appeal
A bizarre puzzle-based mini-game, a number of sidequests, and a couple of hidden goodies should keep you busy during the game's 40-50 hours.

8.0
Impressive OVERALL
(out of 10 / not an average)

Xenosaga I got an 8.8
Xenosaga II got an 7.9

So .8 below the first, .1 above the 2nd.
