I personally found TFU2 to be an absolute disappointment all the way around, save for a few more (admittedly cool) force powers such as rage and mind control. I didn't find the playing experience as good in TFU2 as TFU1, probably because I have the Wii system and in TFU1, you actually controlled the lightsaber movements, but in TFU2, all you have to do is repeatedly press the A button to fight. Plus, the no map thing in TFU2 got really irritating, especially during the part aboard the Salvation where you have to navigate through the laser beam rooms.
The biggest disappointment was how short TFU2 is. It only takes place in three different settings (Kamino in the beginning and the end, the Palace, and the Salvation). Quite frankly, TFU2 was so short that it could have simply been an add-on to TFU1.
Also, I liked TFU1 as much for its compelling story as I did for the game play. The story in TFU1 was interesting and fit very well in to the entire Star Wars saga, as well as answered a question I always had about Empire Strikes Back: if the Sith only come in pairs, why was Vader so eager to turn Luke to the dark side, when doing so surely would have meant the end of Vader? TFU 1 answers that question in a very compelling way.
TFU2's story line, basically, is that Starkiller's clone fights a lot of bad guys because he's desperate to get into Juno Eclipse's pants. THAT'S IT!!!! THAT'S THE STORY!!!!!! Unlike its predecessor, the (light side) ending of TFU 2 pretty much goes nowhere (actually, I liked the dark side ending a lot better) and doesn't provide any sort of insight in to the main Star Wars saga at all.
All in all, I felt ripped off by TFU2. I'm sorry I ever bought it. I should have just blown the $60 at Atlantic City.
