While it may not be the longest game, it is a truly great game.
Having placed these caveats on the beginning this is one of the better, if not the best games ever produced from a movie franchise.
For starters the opening chapter, is basically bad a**, where you get to play as Darth Vader which has all force power maxed out, although it is a little disappointing getting into the story proper and staring with a much less powerful Starkiller at your disposal.
The game is a graphical masterpiece and is a faithful reproduction of locations seen in the movies. Felucia and the junk moon(whose name escapes me at the moment) are specifically beautiful in their own way.
The combat can feel a little clunky at times and the targeting system is not as precise as it needs to be, this doesn't change the fact that some of the moves that can be pulled off are cool. There is some further issues when you find yourself in tight spaces once again with the targeting system. On the plus side freezing enemies in Carbonite is extremely satisfying, and the combos are really cool, as mentioned earlier.
There is an alternative ending that is not terrible and is pretty cool to see but you'd be better off saving and reloading rather than play through twice.
The characters are all interesting and some old favorites appear, and it fills in the creation of the Rebel Alliance which for Star Wars fans make this a must play.
The game has very little incentive to play through more than once, the collectibles are not really that good that you feel you have to get them all and while it is good you can have maxed out stats once you have played through once is a nice touch but one that is fairly redundant when all is said and done.
This game will not win any awards, but it is a truly great franchise game and one of the best Star Wars games. If Lucas Arts can make more games like this the Star Wars universe is in good hands.
