As I've mentioned before I'm not really big on any of the romance options, but I appreciate a lot of people are and my thoughts are this. If we are going to have a romance-able character they should be available to the PC. Regardless of race, gender or anything else, this is a GAME and the PC is the star and if you want to romance character X because that is your story then you should be able to.
Now I know Bioware are talking a lot about how the story makes sense of their choices and I say simply Bullshit.
One of the first things you learn in pen and paper RPG's is you put your PC's first, not fall in love with your vision of the NPC's at the expense of the PC. The PC is king (or queen) and as far as I'm concerned every option should be open to every player IF they want to take it up, and for it to be easily closed off if they do not.
Personally I'd hate this. One of the enjoyments for the rpg game is being different characters with different interest and ideas. If all romance interest are available no matter what my character is like, that's a big disappointment. Why bother with the different playing ideas if everyone loves you no matter what kind of **** head you are.
DA2 was my least favorite romance group. Everyone would fall on their knees in Hawkes present no matter how they were treated. NPC hates mages, rival them. NPC hates templars rival them. Everyone will love you. Ick.
Now if they set it up so that the romance was based on your characters decisions instead of gender, I could get with that. But I hate having them all want to go after my character no matter what. I don't want my character to be King, Queen or the Love Spider goddess with the power to pull everyone into their web. Just no thanks.
