Way too short. No variety. No substance at all.
I've played DLC longer than this game. In fact, the 3 DLC packs from the first Force Unleashed (which I enjoyed) are much longer, more interesting and have more variety than this entire game. One of the nine chapters involves walking 2 seconds to Yoda's hut, cutscene where Yoda say like two sentences, cutscene in a cave, done. That's one of the nine chapters! There are three playable levels in this game and they recycle two of them! I enjoyed how in the first game you went to worlds hunting down Jedi and then came back after they were conquered. In this game you travel through a ship being attacked by two types of droids, then the very next level travel backwards through the same ship being attacked by the same five types of storm troopers you've fought all game long. That's shear laziness.
People are saying, "Yeah but the first Force Unleashed was short". No. The first game was a decent length. This game is absurd. It's hard to get over what a huge rip off this game is to even start to review it but here it goes.
Graphics are nice. The combos are better but you move so slowly in the game that you never get close enough to anyone especially on Sith difficulty. I heard somewhere that they improved the targeting when you pick up stuff, but that certainly is not the case, it's noticeably worse than the first. The Jedi mind trick is awesome and makes me laugh. Kota sounds like an idiot. Sith difficult is stupid because your health doesn't regenerate but whenever you die the game brings you back with full health. Since checkpoints are very generous in this game dying is actually a huge benefit. I was dying on purpose just to recharge my health. The end fight is one of the dumbest boss battles of all time. Not frustrating or difficult, just dumb.
The age old Star Wars question becomes glaring obvious in the last level; why can't Jedi fly? If you can lift effing starships why the heck can't you lift yourself to the top of the level. Or at least hover a little rather than jump jump dash. Or at least grab onto ledges instead of sliding down everything like it's made of ice. What I'm getting at is that the platforming is terrible.
Now the game does have a whopping ten challenges so here is my rant on why I hate challenges in games. First off it is lazy. It takes a lot of effort to build story, atmosphere, level design, level progression, etc etc. It takes no effort at all to throw the main character in a single room and throw enemies at him with different victory conditions. It's like the Mad Moxxie DLC for borderlands. Pure laziness.
The second reason I hate challenges is because it takes whatever flaws exist in the controls/gameplay and magnifies it. And there are a hell of a lot of flaws in SWTFU2. A few examples; there is absolutely no rhyme or reason to when he deflects missiles. Sometimes you press it just before a missile hits, sometimes to press it and hold it, sometimes nothing works. But you can get through the game not noticing this flaw. Now if you get placed on a small platform and you have to deflect five missiles coming at you for six minutes you're going to be pulling your hair out. Having trouble pulling off the jump, jump, dash, force push because it only works a quarter of the time? Not a problem because you don't need it in the game. But try the challenges that force you to pull it off in quick succession and you might as well put your fist through the television.
Okay back to how short this game is. There's no story at all. If you watched two commercial you have the entire plot already. In the end they don't even answer the only question asked by the game's story and they have the audacity to leave it open for a sequel. The "choice" at the end is the most meaningless, throw away, pointless decision in a video game ever. If anyone calls this last minute, tossed in, menu screen a "choice" they should get their head examined.
Save your money for all the amazing games coming out early 2011. Don't buy this game.
