I'm basically a romantic and BW is the only game developer who gives me the fix I want. Enjoyed ME1 romance scene with the lighting, music and romance with a loud R, much more than DA:O and DA:O much more than DA2. But I did like being able to talk to my LI whenever I wanted in DA:O, even if all they said was "yes love?" And yes, kissing your LI or giving them a hug anywhere other than battle would be great. My husband still holds my hand and kisses me in public and it's very nice. I also enjoyed the others making little comments, it made me smile.
I didn't care for the romances in DA2 as much. I liked that they were different from each other, but I got really irritated with them just standing at the top of the stairs and not talking to me, and Fenris, when I did his romance, it brought back the image of a one night stand. Not romantic and not my idea of a good relationship. Even Morrigan with her issues was better (imo) than Fenris. And I liked Fenris as a character.
I know the romance in their games isn't loved by everyone, even though they are optional, and I also usually play at least once without doing them, but for me it does make a difference if two games that look good come out at the same time, I've always picked BW first the the other one later down the road. Without the romance I'm not sure which I'd pick first.
Saw someone mention this - Friendship conversations with everyone. Yes, throughout the whole game. I laughed every time I talked to Lelliana about hair and shoes (I used to have a rather large collection of shoes myself). And showing my character interacting with the others would be great, even a group, which would change so could be done a couple of times, is playing a card game and invite you over, you can say yes or no and if you say yes it shows the sun coming up through a window, the group breaking up and sometimes you win, sometimes you lose and sometime break even. Or something.
