Ok, but once you get over all the new stuff, the game gets really repeptive.
Unfortunately, you can only play as Starkiler, but the game features a good amount of customization, such as lightsaber strength and color, force abilities, combo attacks, etc. You can also unlock costumes by beating levels and finding Jedi "holocrons", which appear as glowing whiter boxes hidden in the levels.
The graphics aren't that good but almost everything in the levelcan be destroyed and you can go back and do levels over again. The game features a good amount of enemies, too. There are several familiar characters (Princess Leia, R2-D2, Shaak Ti, Vder etc.) but there are many new characers that have never been introduced. Juno Eclipse, Starkiller's ship pilot, seems new but was actually in the game Sar Wars: Jedi Starfighter.
Sadly, even through all the publicity such as through GameInformer mag, this game gets very repetitive once you learn all the secrets and moves in the game. Once you beat the game and get all the upgrades, the game is not really worth playing again.
