Man. A lot of flak flying around here. Need an armored vest just to state a bloody opinion...*pulls on flak vest*
Okay. This is still a videogame. And without some alien technology introduced to perfectly model the behavior of human beings, we aren't going to have any game that shows a character that acts like a real person. They'll just act like characters with dialogue written for them by some guy in front of a computer. If you can get past that limitation, then you can enjoy what is written for what it is worth. or...not, if it's written poorly.
If a person feels the romances in KotOR were poorly written, and would not like to see more poorly written romances, that's fine. Personally, I'd rather not see poorly written anything. If the writing sucks, the rest of it won't be enough to hold my interest, romance or no.
If you're holding out hope that you will have a romance in a game with a realistic character, that is not logical. If that is discouraging you from the game, worry about something that you can actually change. If you're holding out hopes for well written characters, I'm right there with you.
Of course, I may be biased because, for the most part, I thought KotOR's characters were written well. And I have no reason to think that the sequel's characters won't be written well.
As to the inclusion of romance options:
I have no reason to think, as of yet that this is being ignored. Game romances are amusing, and can be an entertaining facet of CRPGs. I don't feel they're so intrinsic to Star Wars that the game couldn't stand without romances, but at the same time, as the player, you always have the option to love or not to love. So why not include them? I never pursued a romance with Aerie, but that didn't affect my enjoyment of BG. Same with Viconia. But I know people who did. And who enjoyed those options.
Why not include the option?
