I definitely felt Origins did better in the romance department, though they had their flaws/glitches, too. Loved Alistair's the most, but it felt like you got to the best bits earlier on in the relationship, and Zevran's gets better near the end, but his end-battle dialogue is so buggy!
In 2, Anders is my main pick. Hits you a little more, the ending, if you romanced him, but in a friendmance, found his end-dialogue pretty lacking. The most satisfying, for me, was Fenris, but I guess I enjoy drama, because end up picking Anders usually.
But they still didn't hit me the same way, the romances.
I feel in Mass Effect I was hit more for a romance, because you potentially can carry over the same romance or friendships thru 3 games, so you -really- get to know them and care for them.
When it's just one game, they really need to pack a punch.
Since so many were angry with DA2 and the Mass Effect 3 endings, they're gonna have to really step up everything in DA:I, and I think they will.
Many have worried the character development or writing will take a backseat because of all the talks of pretty environments and graphics, but I think enough anger has been thrown at them in regards to story related things, that they might be more careful about that, they seem aware of how much people give a damn about their characters and stories, and with all this extra time they have on it, hopefully they're able to really flesh out everything and make it all better than it was before.
Since the plot seems to really rev up that drama much worse than previous games, your character's gonna be bombarded with bad stuff happening. End of the world all at once, not just one country with problems, all countries with problems, etc. etc.., they're gonna have to really give us someone special to share the load with.. or since this is a BioWare game, probably someone who makes the burden heavier to carry. Definitely expecting some emotional impacts.
