Characters are MUCH better than the ones in the first game. Like, much. The writing itself is considerably better and strike a better balance between funny and serious (the first one was a bit overtly silly IMO, though the main story was pretty dark).
You do lose a bit making a custom char, because each predetermined char has his own story that he's following on top of the main one, but then you can not play them all at the same time so if you really want to see all the story in depth you'll have to play them all
(it's still pretty much sidequests, so it's not a big loss, and I'm still playing a custom character anyway)
As I said in another thread, the main criticism I do is that the fights are quite overwhelming (at least in the beginning) and the number/items inflation is just stupid. Save for that, it's really good.
I never played the original. Does anyone have it? Care to do a little review on the old one or the new one?
I have heard it compared to old school rpgs with turn based tactical combat based on d&d. Ouch. That sounds overwhelming to me. I tried to get into neverwinter nights 2 and just couldn't do it. I didn't know how to build my hero to do damage or how to move (what are these strikes of opportunity killing all my guys?) So I'm trying to figure out if this game will appeal to me or not. I loved dragon age origins, da2 was ok, but those are very rpg lite.
Both OS are HEAVY on the roleplay side (OS1 has even a very interesting twist, where you create two main character and you can roleplay BOTH, even arguing between themselves). They are also TRUE RPG, that is you're not just chosing the tone of your answers, but your acts and answers can actually have consequences - it's much closer to Fallout than Dragon Age in this aspect.
They are really old-school, in a good way (no handholding, no infodump, you feel clever when you find an answer and you slowly discover the world). Haven't tried the EE of OS1 (supposedly they improved the writing and the characters), but even in the non-EE state it was already a classic.
They also are HEAVY on the tactical fighting, and really challenging (like, plain HARD). Of course half the braggarts on Internet will claim they found the normal ("classic") mode "so easy they could finish it asleep" and the hard ("tactician") mode barely challenging, but either they're clearly not representative of the average gamer, and/or they're, well, braggarts trying posture.
If you found NWN2 too hard, just go with easy ("Explorer") mode from the get-go.
And both game happily accept mods, it's rather trivial to make your characters overpowered if you want it (though the fighting system IS really interesting).
