Just finished playing through it... some quick impressions.
Audio is good. They seem to have had a limited number of voice actors, because, unfortunately, a lot of npcs use the same voices. But, fortunately, the major npcs got unique voices. I noticed it easily, but it didn't bother me too much.
Voice acting was Ok. Didn't really think much about it, which at least means it doesn't suck.
The music is beautiful. Just beautiful. I'm in awe.
Graphics is great. Everything looks very nice, especially for an cRPG, though there might be graphically more advanced games out there (like Crysis). Artistically it's top-notch. The areas looks great, in that "I want to enter the screen and visit the place" kind of way.
Unfortunately a lot of npcs share the same model but, again, I didn't mind too much (though on a few occasions it got confusing when different npcs I had to talk with shared the same model and voice). The models, and faces, do look nice though.
Camera took a bit time to get comfortable with but I worked out in the end. Got 3 different modes, and I mostly switched between a strategy style one for when fighting, and a 3rd person style view (with character on left side of screen and camera behind) for when running around.
As for the story and gameplay, I was hooked from start to end.
Many of the choices you make have noticeable effects on the story. Some minor, and some major. Dialogue choices you made in the first chapters of the game affects what is said in the later chapters. Not always things that directly affect the gameplay, but it's cool nonetheless.
There's also various cutscenes/slideshows during the game that looks on the choices you made, or things you did earlier, and how they affected the story. Throughout the game I had cutscenes looking back on choices I made in the start of the game.
Many of the choices you make is also between two evils. There's not a lot of black and white, but there sure is a lot of grey here. Or sometimes just black.
Story is also very nice and I ended up skipping a lot of the optional bounty quests (collect X number of items from Creature A) because I wanted to see what happened next.
Also some good news is that the last parts of the game doesn't completely break apart and turns into a pure hack'n slash (*cough*bloodlines*cough*) nor does it feels unfinished (*cough*kotor2*cough*). At the end there's some questions that never got answered, and people you never heard from again, but hopefully they'll use that for a sequel or expansion. Because I definitely want those questions answered, if possible.
There's a dice game with rules similar to poker (and it's actually called poker) which is kinda fun. Nice way to make money if you're lucky. There's also some opportunities to fight other people, hand to hand, for money.
It's rated M/18+ so some adult content.
It's possible to have sex with various women throughout the game, and after the act (which isn't displayed, beyond a very blurry generic cutscene), you get a card with a less clothed version of the woman pictured on it. Nothing worse than what you can find in any classical artwork, though the nipples are supposedly censored in the US version. Also a few naked or near naked character models in-game.
A fair amount of blood and gore. You'll see heads rolling (literally).
The language is also definitely aimed at adults.
In the end... this have pretty much become one of my favorite rpgs. Up there with Baldur's Gate II and Planescape: Torment and Knights of the Old Republic. I really hope it sells well, because the game is awesome and the devs deserve to be rewarded for it. Anything else would, quite frankly, be a tragedy.
