GIGANTIC potential, good game.
Graphics:
excellent graphics, in the cutscenes the characters look so life-like, the skin, eyes and hair looks amazing, but occasionally the teeth and facial expressions look a bit weird - the environment is very dynamic and if you for instance do force push the plants (or whatever is around) moves. that said there is the occasional bug in the game and frame-rate drop.
Sound:
the soundtrack is as good as you would expect for star wars, it really fits greatly to the game.
the sound effects are good as well, the sound of the lightsaber, force lightning and the classic sound of "Star Wars laser" all sound familiar and great.
Gameplay:
it's is somewhat solid gameplay, with proper use of the buttons - but sometimes when you are attacking and are getting sniped or whatever then you can't quickly dodge - which would seem fairly easy for a Jedi/Sith
Story:
The story is okay, and is made so it could actually fit between movies 3 and 4 in Star Wars, but you just know that it wasn't written before all the movies were finished - but later on to see if George Lucas could milk the "Star Wars Cow" for even more money.
durability:
you probably won't play this game more than two or three times (plus the DLC - but they are so expensive that most people don't buy them).
seems to me they could have made a Jedi vs. Sith online mode - that would have been awesome. (they made ad-hoc battles for PSP)
so this is a very good game that could have been much much greater if they had solved some issues and made that online battle-thing :P
