Okay, I'll make this quick-
Graphics- Very sweet looking during the movie shots, and also very nice during gameplay. The most impressive thing would have to be the overall terrain that you'll go through. Some of the maps are just pure art.
Sound- The only thing a LucasArts game is really gauraunteed to have is good sound. This game has awesome sound effects. There's really nothing missing here at all. I love how the voices are done by the actors/actresses who played the roles in the movie. The most impressive thing for me was hearing the Carbonite moan noise on one lap. It really brought the whole map together as far as environment goes.
Soundtrack- Okay, let me 'mark out' here by saying this... This is the best soundtrack on a videogame I've ever heard. It's got clips of every Star Wars movie to date, from what I have heard. It's got a few ESB Cloud City tunes, the Bounty Hunter tune from AOTC, several tunes from Jabba's Palace and related from ROTJ, and I think, not sure, but the Droid Army tune from TPM. I also believe there is a Cantina tune thrown in there at one point. This is the best part of the game.
Gameplay- Whew... okay... It's sorta fun to play, until you get to... maybe the 4th mission. The game just relies so much on the jet-pack and jumping and all this crap that you end up feeling more like spider-man than Jango. I was very disapointed with the gameplay. There is no difficulty setting, and you are only given 5 continues once you die, and because these maps are so large and enemy filled, you will need every continue to beat the map. It's very annoying to get "close" to finishing the map then to die for the last time and have to go all the way back and re-do the map. VERY LAME. This is also a Button-tapper shooter game, aka, there is no stealth or skill involved in killing someone... Just tap really fast and jump a lot.
Overall- I was really disapointed by the game... I'd buy the soundtrack in a second though.
