I didn't say the be all end all.
Your words heavily implied that without romance the relationships between Player and NPC were null and void, or somehow less than the romance itself. I'm glad to see that I was wrong, and you don't actually believe romance is necessary for character interaction.
I'm also glad to see that, despite the fact you seem to contradict yourself, you agree romance is not the only "rich" form of interaction. As you have said there are a number of ways to build relationships with characters, ranging from friendship to rivalry to romance.
Completely unrelated to my misinterpretation of your words and for the topic of Romance itself I will attempt to voice my opinion as clearly as possible with minimal use of bile:
Romance is not a necessity in the grand scheme of interaction, but it is one of many options available to a Player and I can't fault Bioware for giving us options. Friendship, rivalry and romance are all *optional* choices of character interaction. Each person is going to want to pursue a different avenue and each of those avenues should present it's own challenges, contain it's own progression and have it's own unique conclusion.
The problem that I have is the fact that the only path to gain it's own unique content, it's own fitting conclusion and it's own presentation of unique challenges is Romance. Romance receives more content than any other form of relationship, yes it's all "romantic content" meaning that anyone attempting to pursue a friendship "shouldn't care", but the simple fact is that that "romantic content" means that Romances get a greater sum of content than Friendships or Rivalries.
If the relationships were well balanced I would have no problem. If Friendships and Rivalries received their own unique dialogues, their own suitable conclusions and their own challenges to overcome then I would have utterly no problem with the continued use of "focused Romance". But the simple fact is they don't. The optional interaction of Romance receives more care, attention and CONTENT than any other form of interaction and I consider that to be rather ridiculous and entirely unfair.
That being said, I've come to accept the fact that Bioware are incapable of presenting each form of Player/NPC relationship with the same care, attention and content as Romance. So I'm willing to completely overlook the blatantly overbearing romantic content that overshadows every other form of interaction.
