This game sports of some of the cleanest graphics I've yet to see in a Star Wars title. Characters like Anakin, Obi-Wan and Dooku look just like Hayden Christensen, Ewan McGregor and Christopher Lee. Even the enemies like the droids and clones look like the big-screen counterparts. One of the Episode III's shining points is when you go lightsaber-to-lightsaber. The effects between the crossing blades and the various attacks and parries that are shown in the characters' animations are just wonderful. Unfortunately, once you're out of the combat aspects, the character animations become a lot stiffer than you'd expect.
The only other thing I have against the game's visuals is that there were times when the graphics were too clean. Early on in the game, when the two Jedi are running through the hanger of General Grievous' flagship, there is a massive space-battle going on through the windows. Every time I passed one of these areas, I was in awe at how much detail I could see in the ships, but that seemed unrealistic. At the kind of distances these ships were at, I shouldn't have been able to see things as clearly as I did, and it was a bit distracting at times.
Like Star Wars Battlefront, you will be treated with cut scenes straight out of the film, which all-in-all is a nice touch for people who really liked the movie.
The audio department isn't lacking either. Though it doesn't sport background music from the Episode III movie soundtrack (the music draws mainly from the previous five movies), each lightsaber hum, dark-lightning crackle and robotic-beep is as authentic as can be.
