Well I know I wouldn't. Though, not everyone is as beautiful as I am, so I figure some people get desperate.
I've got to admit, I got about four or five pages in to the thread and skipped to the end so I apologize if this point has been made but given how formulaic romances have typically been within the genre, I'm almost glad they aren't going to be included. It got to a point, especially in Dragon Age, where I cared less about any emotional investment in the story arc and more about "oh *%$&£, I've got to say the right thing here - or I'll miss content." That in itself completely ruined any immersion.
I'm all for character interaction, it's what made BG:SoA so amazing and it's why IWD always felt a little soulless but if you want to really immerse yourself you need to be free to pick dialogue options and take character relationships in a direction that you feel appropriately correlate to your perception of this character you're trying to play. When you're shackled by "you've got to get in her pants if you want this sweet +3 longbow" or "bang the drow cleric if you want her rewarding side-quest" it loses a lot of it's merit.
