There was this one brilliant LP that went through all the niggling backstory details and brilliant storytelling going on in KotOR 2, as well as all the cut content.
His comment on Atton's first dialogue about his past went something along the lines of, "You ever have that awkward, weird friend that you kinda like but you also don't think that highly of? And one day, when you and your friends are joking with each other, you make fun of him, and all of a sudden a switch gets turned and that shy awkward guy becomes the most terrifying person you've ever met and snarls at you and you're all just sitting there going, "Holy ****, what just happened?"
Atton is that guy."
I don't judge Loghain that harshly for being screwed up because Atton was my bestie back in the day.
Hahahaha, yeaaaah. I still adore Atton, for all that he's incredibly screwed-up. The guy's just so damn likeable, and I have a soft spot for characters who are so obviously devoted to the character I'm playing as. No matter what you do, Atton loves you. Whether you're a puppy-kicking monster or a complete goody-two-shoes. Which...also demonstrates just how messed up he is, now that I think about it. 
"I loved her so I had to kill her" wasn't disturbing or anything, oh no...
I miss Atton
. I was taken from the moment he was perving out on my half-naked Exile. Ha 
"I found some clothes"
"Dammit!"
I miss him too. He was such a breath of fresh air in that first level. The only one around who it seemed like you could trust.
A while back I downloaded an insane number of mods for KOTOR 2. Mostly appearance stuff. And the game looks gorgeous with just a bit of polish. It's still receiving mod support too, even after all this time. Someone released an HD texture mod for Atton not too long ago.
Sonovabitch looks good.
I mean, there's only so much you can do with a ten-year-old game, but it holds up well. Blah, now I want to play KOTOR 2 again.
I loved Atton, and the tangled mess that was KOTOR 2. I really need to play the restored version someday.
You should! Especially for the restored content at the end. Do you know what they put back in? The stuff concerning Atton is amazing.
I got the PC version recently just for that. 
I don't like the controls at all, though.
I'm currently struggling my way through Nar Shaddaa.
I originally played on a console, so I know what you mean, but I got used to them. It helps that it's easy to do pause 'n play during fights.
And ahhh, Nar Shaddaa. My favourite world, but also the most frustrating.
