Liked:
Atton - Like the rest of the crowd. He was no competition for Carth - but he was the smart wise crack that you needed in the beginning of the game to help ease the constant talking and lecturing of that 'manipulative witch' Kreia. Atton had an interesting story - but when I heard it, I didn't necessarily feel like I earned enough influence with him to hear it. After I confronted him on Nar Shadda, he just opened up and started spitting it out all at once. KOTOR I was a bit more realistic to me, because I had to work with Carth (even though it was painstaking at times). And when he finally talked to me about his past - I felt like 'Finally!' but with Atton it was just there all at once. Like the rest of you, he was funny but not developed enough.
And yeah, it was a *little* too easy to convert this Jedi assassin to the light side - a little too easy to convince him to become a Jedi - I mean, if he hated them so much.
Mira - Oh thank god for this character. She was the badass chick I was looking for in this game and the first (Since you know, Juhani and Bastila no matter how cool they were, just weren't bad enough and Mission...well When playing as a Female, she talks about how to handle men - which is cool. When playing as a Male though, she tends to get more on the 'eh' list. Calls you old but when you read her mind she's like 'how does he look so young?' Doesn't make sense to me either - but she also has her smart alleck cracks, like Atton.
Visas - Although you don't get to talk to her much, she was the *coolest* female character in this game. Mira was awesome with her attitude persona, but Visas just struck me as the cooler girl.
Hk-47 - He didn't provide much of a story in this game like he did in the first, but he still had the funniest remarks I've ever heard. Talk to him about love - and that's all you'll need. Or you can install the pacifist package in him...that's a good one too.
Darth Sion - This guy was kickass! Seirously, I wanted to encounter this guy more than what I did. His voice was suited IMO to his character. I thought he was developed pretty well.
Disciple - He was a suck-up...and I'm a sucker for those suck-ups. Extremely nice and full of comments. Tries to protect your Female PC when he realizes who Kreia really is - but it all seemed played up. Didn't feel sincere enough to me - despite his strength and beauty lines.
Handmaiden - She is one tough chick. Her skills with the sword and dual lightsabers is insane. She kicked Atris' Jedi ass in my game and still got zapped - not cool. She also had quite a few sparring lessons with you which helped out in the battle circle on Dxun. Her story is semi-interesting but like the Disciple she's ready to throw herself out for you at any given moment and she doesn't really *know* you.
So-so:
Bao-dur - He was crazy with the computer and demolition skills. Helped me out a lot when I was er- 'lacking' in those areas. I thought he was pretty wicked with his cybernetic like arm, and I thought 'Yay! A cool-beans character that I get to crack open and find out about'. NOT THE CASE. You only get to talk to him so much, then he shuts up. Kinda like the rest of them - except Kreia - she ALWAYS has something to say.
T3-M4 - Cute but could tend to get annoying with the constant beeping. He was more useful in this game though, gotta give the little guy credit for that.
Mandalore - Although I was and still am a huge fan of this mandalorian, he just make it to the like part of the list this time around. He was a mediocre character - little involvement, little to say. Still, his useful ness in a tight spot was handy.
Kreia - She was manipulative, but she wasn't actually so bad. Teaching you so many force abilities and helping you deck out your character was a plus. She's actually pretty easy to gain influence with, you just have to know how to work the edges.
Disliked:
G0-T0 - Just completely useless. A pain in the butt, with a voice to compliment his devoid aura of personality. He would've been better use to me as spare parts or maybe in the trash heap.
Darth Nihilius - This guy could've been so much more, yet was denied. His look was really neat, and his lightsaber skills (when you do fight him) were insane. But the interaction time you get with him is nada - and he only appears in the game about three times max - if even that many but his face is on every thing KOTOR II. Nihilius for me would've been the preferred last combatant of the game - but you never get to the extent of his power which was a huge letdown.
Atris - As soon as I finished my convo with her when I arrived on Telos, I wasn't much impressed with her. She was boring, and was over advertised like Nihilius. Like him, she didn't provide much of a role in this game other than additional meat to slice.
