There was a lot that suffered in DA2 but the writing was still pretty good. Also, go back and play games like Baldur's, NWN etc...there are plenty of romance elements, and while they're not as "in your face" as DA2 Anders was, (and just for the record, NO ONE is as bad as Anders) there are still plenty of instances where they will bring in romance without you actively seeking it. As an example, despite choosing all the chaotic evil options for my rogue/assassin/shadow dancer in NWN2, Casavir, the lawful good paladin STILL fights over me with Bishop. And bitches be tripping, cuz no one can hold a candle to Bishop.
ANYWAYS...DA:O was very well done; it wasn't a new Baldur's Gate, but then again, if you expected Baldur's Gate when it was clearly marketed as a "Spiritual Successor" and not a straight up sequel, then you're probably not altogether right in the head anyways. DA:O was a nice touch back to those RPGs of yesteryear, and I loved it. It was close enough to the old RPGs to draw me in, new enough to keep me interested, and different enough to keep me entertained.
Props for listing Planescape though because holy shit, that is STILL my favorite RPG of all time and if you love RPGs and haven't played Planescape: Torment, I think you go to a special level of hell when you die.
Edit: I also don't understand how DA:O wasn't considered a spiritual successor; what did people want? It gave me the same good vibes I got while playing BG; not as accomplished but still in that vein.
It's done "in the spirit of", not necessarily "exactly like". I don't really see the problem with the deviation. Would I have loved something closer to BG? Of course; those RPGs rate extremely highly in my book, but I found DA:O to be very good in it's own right. Hell, DA:O even had enough of a difference in endings to rival Mask of the Betrayer for NWN2. I mean, Mask was fucking phenomenal, so I won't place it right beside it, but a good show nonetheless.
