I really disliked the first KOTOR as it had boring gameplay, an environment in which you only had limited interface, and the a predictable and boring storyline. Because the game engine being used did not change from KOTOR 1 to KOTOR 2, KOTOR 2 also suffered from boring gameplay and a limited interface. But the story... my god that story and the characters were unforgettable. The voice actor who voice Kreia still gives me chills when I hear some of her lines from this game. The ending was a let down until I played with the release of the 2011 mods and enjoyed the restored content. With the restored content, KOTOR 2 has the best Star Wars story of any fictional media I have experienced. I would even put it above the original movie trilogy (Episodes 4, 5 and 6). I still can't enjoy KOTOR 2's gameplay, but I would willingly suffer through it just to experience the story once more.
My top Kreia quotes:
"It is such a quiet thing, to fall. But far more terrible is to admit it."
"Step away from him! Step away! He has brought truth, and you condemn it? The arrogance! You will not harm him. You will not harm him ever again. As you would pass judgement on him, I have come to pass judgement on you all." (to the Jedi Masters, continues) "How could you ever hope to know the threat you face, when you have never walked in the dark places of the galaxy faced war and death on such a scale. If you had traveled far enough, rather than waiting for the echo to reach you, perhaps you would have seen it for what it was. There is a place in the galaxy where the dark side of the Force runs strong. It is something of the Sith, but it was fueled by war. It corrupts all that walks on its surface, drowns them in the power of the dark side, corrupts all life. And it feeds on death. Revan knew the power of such places... and the power in making them. They can be used to break the will of others... of Jedi, promising them power, and turning them to the dark side. The Mandalorian Wars were a series of massacres that masked another war, a war of conversion... culminating in a final atrocity that no Jedi could walk away from. Save one. (looks at the Exile, who is lying, unconscious, on the grass.) And this is what I sought to understand. How one could turn away from such power, give up the Force... and still live. But I see what happened now. (squats down and looks at the Exile again.) It is because you were afraid."
"Perhaps you were expecting some surprise, for me to reveal a secret that had eluded you, something that would change your perspective of events, shatter you to your core. There is no great revelation, no great secret. There is only you."
