I just finished playing through for the first time so I figured I'd add my own comments to this thread.
For the most part, I agree with Vol's review. I don't know if I'd gush as much as he did. The first chapter was well done and set the tone, but I didn't feel it was extraordinary or anything. It did a very good job of giving "background" for the setting and for what was to come.
The second chapter started giving the PC more quests to tackle and that's when the game picked up. I thought the quests were well done, but one minor complaint I had was it was relatively easy to figure out the "subtleties" of what was right and wrong. For instance, in the Forest section, they were a bit too obvious that the people in the Inn weren't "right" somehow and that the forrest fox goddess (I forget her name) was actually the "good" path. Overall, I thought it gave the player a good selection of choices where non-violent solutions could be used.
The third chapter was by far the best and the least linear of the entire game. IMO, if it weren't for the third chapter, the story would have been way too linear. But the third chapter allowed you (for the most part) to do the quests you wanted to in the order you wanted to, and had massive areas to explore. I was hoping for a bit more behind the Black Leopard School section. The story itself for that section was interesting, but it was a bit short considering it had an entire "area" dedicated to it. Same with the Scholar section. But overall, chapter three was great. BioWare also expanded on the KOTOR dueling ring by implementing a deeper aspect with the Imperial Arena. It took the duels from KOTOR, but also added plots and subplots to those duels, which was a great addition.
Chapter 4 to 7, IMO, were a let down. The story itself during these chapters was still interesting, but it felt like from Chapter 4 until the end, it was just a mad scramble to the end. You knew what was coming and it was just a matter of fighting your way there. The roleplaying and subquests pretty much end after Chapter 3, and then for the remainder of the game you're just wrapping up the story. It was more well done and fleshed out than the endings of KOTOR 1 and 2, but it still reminded me of from about the Unknown World (Rakatan world) until the end of KOTOR 1, and from about the Jedi Enclave meeting with the Jedi Masters until the end in KOTOR 2.
Characters:
I thought they were well done, but I don't think they were exactly memorable ones, mainly because you could only bring one along with you, so often times the rest weren't part of your party. I thought Silver Fox's character was great, since she had such a direct tie to the story, and up until his "sacrifice", Sagacious Zu's character was intriguing because he had a secret to tell. But, IMO, the others were just "there". I was especially disappointed with Dawn Star's role. The first couple of chapters built her up to be like the main sidekick for the PC, and built up her story to make her something important, but unless I missed something major, I never saw her background explained fully. There were hints (such as the chat between Sagacious Zu and that chick you meet at the Tea House in Tien's Landing), but her storyline was sort of dropped once Silver Fox joined the group. It almost felt like Bioware initially wanted Dawn Star to be the main love interest, but then said "nah, we like Silver Fox better so we'll use her".
Villains:
Very well done. Some of the deepest villains I've seen in a video game. Their stories were fleshed out, for the most part. For instance, Gao the Lesser wasn't just some "endboss" you had to go through for the sack of having someone to fight. He actually had a deep backstory that was told. Same with Death's Hand, and both Emperors. Even the minor villains like the Serpent guy (the arena endboss) was more fleshed out than most other game villains.
Combat:
I enjoyed it. I'm not a big fan of twitch gaming, but the controls weren't cumbersome and weren't tricky at all. I think why I liked the combat in JE and not in BL was because you could automatically "target" your enemy in JE. So as long as your enemy was targeted, it was near impossible to miss with a hit. In BL, it felt like you had to get the enemy lined up, which for someone like me, got annoying when they're swinging away and hitting and I'm struggling just to get the target recticle on them.
Dislikes:
-Linearity of the story after Chapter 3. As I stated above, even though the story didn't actually fall apart, rather it just kept going at a good pace, the game went from a roleplaying game to an adventure game where you basically spent most of the time fighting various enemies.
-Projectile shooting enemies. Ugh! I know this is more my own flaw rather than a flaw of the game, but since I rarely used the block button, projectile enemies gave me more trouble than anyone else. To put it into context, I had more problem with those tainted spirits that shot that green fireball at me than I did with the final battle against Sun Li!!
-NPC party members in combat. They were next to useless. The only purpose they served for me was distracting an enemy or two when there were large groups attacking me. That way I could finish off 3 or 4 enemies while they were busy getting killed by 1 or 2 of them. They were basically a diversionary tactic for me rather than actually helpful in combat. Except for Whirlwind. His axes were great against lesser foes.
-Load times. Annoying. Although they gave me a chance to flip back to checking the baseball scores on TSN while I waited for the next area to load.
-Game length. Yes, I felt it was too short. Even in comparison to the KOTOR series. Both KOTOR games took me over 30 hours on my first play thrus. My last save had me at 25 hours and 52 minutes, which was right before the final fight with Sun Li, so tack on maybe at most another 10 minutes and there's my playing time. I think if they maybe had dealt more with both Sky and Dawn Star's past, possibly even a side-quest for each, it could have increased game length.
I think that's about it. Overall, it was a great game.
