Reasonable 3D graphics, good sound effects, but the great gameplay (lightsabers!!) more than makes up for the shortcomings. And there're tons of FMV to watch. Unlike other games where FMVs were either put in as an afterthought or overdone, the ones in JK are seamlessly integrated to the flow of the game.
Levels are huge, so be prepared for long load times. The levels are very well-designed, giving an immersive feel. The Multiplayer levels are especially great for lightsaber fights!
Don't miss it!
