I for one made a point NOT to get close to any Forums prior to playing K2 - as I had accidently stumbled up on the revelation in K1 prior to reaching that point in the game....arrrrrrgh!!!
Without getting overly picky, after completing K2 my initial take was:
1. The overall quality of the game was okay - I had very few bugs that I noticed.
2. Many of the larger aspects of the story itself were messy to say the least. I don't need a dev to spell everything out, but a general idea of what was going on would be nice.
3. Some worlds seemed much more complete than others.
4. Many of the characters were underdeveloped - particularly the Sith Lords and Atris - which after being plastered on all of the promo stuff all year was surprising.
5. The ending was inexcusable. Not because it left me "hanging".....but because it was totally hacked and left me more confused than anything else. An open ended story leaves you thinking....."hmmm, I wonder what's next"....K2 left me thinking "that's it!?!....WTF???"
Simply put, I really think that Obsidian got overly ambitious with the story and would like to believe that if they'd managed their time better we would've gotten a deep and provocative tale. Yes..I place the blame at Obsidian's feet as they already had the engine and knew the timeframe when they took the job.
K1 wasn't overly complex in its story or structure, but what was done was done very well and with a level of polish that made for a very enjoyable experience. K2 gave me the impression that it was born of good intentions, but was allowed to get a little out of control during the process.
I enjoyed K2 in pieces, but as a whole it was a letdown. Not due to what I read in the Forums, but due to its chaotic framework and the simple, gaming masterpiece that it was being compared against.
