Favourite romance?

I think you answered my question.

You can say, that Anders is single-minded, yes. This is why I said: he has many flaws, but he's not selfish. True, in Kirkwall, he was forced to be single-minded: Kirkwall was the centrum of his problems. (Fenris seems more open-minded, but I'm curious, if we would in the centrum of slave trading, Fenris would more open-minded to a peaceful solution with them... For example, to prove to them that slaves are good people, and deserve freedom, as the stupid rival!Hawke advised to Anders.) He lies and tries to manipulate Hawke, because his cause important to him, and can't trust anyone. He has very bad experiences with trust, he shouldn't risk his cause with trust, I understand him. And he doesn't break up with Hawke, if Hawke refuses to help him. One thing, why he able to break up/doesn't able to start the romance, if Hawke let sloth demon to possess Fenyriel.

The Chantry destroyed much more innocent lives, than Anders (if course, the Chantry destroyed lives according to the Chantry's own law, so: the Chantry is right, because destroying people with "lawful" tools is right thing). A war required lives, and he tried to find peaceful solutions, Elthina caused the war.

Anders' friendship romance with a supportive Hawke is the most romantic romance in game ever. It's not heart-breaking: two outlaws going from Circle to Circle and set the world on fire for freedom. This is the best moment in Inquisition, when Hawke speaks about it.
I did Anders romance as a warrior too, and this is a bit different feeling (It's worth to try), than as a mage. As a mage, they are buddies, brothers, as a warrior, Hawke can try to understand and feel him, and to protect him. I don't know, which version I liked better.

I never killed him in romance. I prefer the happy end. And never tried the rivalry romance. His rivalry romance is terrible.

Yes, at the end he's even more impatient and rude, and lose his charm and humour. Because he's a "normal" man, who prepare some terrible thing. Just think about it: a psychopath would behave "normally", I think.

How? Merrill's ~20, when Hawke meets with her, and ~23, when the romance fulfill. Okay, she's the youngest, but still not a child. (Isabela 30+, Fenris 25+, Anders 32? at the first meet. Hawke ~25.)

He is right though - Merrill looks like a child. I never did the romance nor am I planning too. But if I would consider romancing Merrill, I would have to look for a more mature head morph, otherwise, it would just creep me out.

She can't handle people and live in her own world, but she's not childish. She's rather an absent-minded scholar, than a child (Liara too...).

HYR , fylimar :

I never saw her as a child, but ofc, this is just a feeling, and feelings can hardly be argued, I just said, that I always see her as a "scholar", who is just one thing interested in, and when she comes out from her own world, she just wonders, yes, like a child, but this doesn't make her child. It was a disappointment, that how easily the demon deceived her, I think, this was a bullshit, so: I will not take her in the Fade anymore...

Maybe she looks like a young teen, but not Hawke seduces her, she needs only one innocent flirtatious sentence, and she appears in Hawke's mansion, just as Isabela. (I think, this is an idiot concept, –for Fenris and Anders must confirm that Hawke really wants them, before they appear in the mansion– since then I experienced, I don't say one flirtatious sentence to her. Quite uncomfortable to send her away.)

Many elves look like a child, because they are little and doesn't have a normal body (especially in the Inquisition –I don't like to play as an elf in Inquisition due to this reason–, but Fenris also skinny enough), and they have big eyes.

I can agree, that probably some perverts can look at them as a fetish. I do not really find them sexually attractive. (Except Fenris, because of his temperament and voice, but not at first sight – at first sight he was only an annoying boy, carrying a bigger sword than himself, and constantly brooding, while spoke stupid things. Later I heard his stupid things, and realize, that they aren't so stupid, and he's more fun, than I expected and very passionate.)
