I grabbed the PS3 version when it was on clearance at Target, and the game was a mixed bag. The story was actually a decent bridge between the Prequels and Original Trilogy, but I quickly got annoyed by a bad combination of sluggish controls and ledges of instadeath. To me it just kills the game for me when a supposedly badass Sith warrior falls to his death because you hit the attack button one too many times and you manage to send yourself flying off the ledge because you thrust too far forward with you lightsaber jab.
Even more annoying, the game designers had a bad habit of making the respawn point before boss battles just a moment before a too long unskippable cut scene, so after you died a cheap death during a boss battle, you kept having to rewatch the cut scene before you could get back into the action.
The game had a lot of potential, but ultimately a lot of sloppy bits did it in. If they put a little more care into the game it could have been as good as Arkham, but instead they just churned out a frustrating platformer.
