I'm all in for Romance options, I don't see how this will hurt the game experience for anyone.
HOWEVER, I don't support simplified get-go unrealistic romance (read harem) options. Just because I have a NPC of the opposite gender in my party it doesn't mean that this character's sole reason for existense should be defined by my ego stroking urges.
I totally want there to be romance options in the game and while I did like some of the romance options in BG2, I think that if there is such an option in PE it should be closer to what Planescape had. When you are nearing the end of the game or a party member's personal story arc, when you have invested a lot of time into understanding this chracter and have formed a bound with him/her only then should that option be possible.
I don't want a Date Tycoon game, I want a mature and intelligently writen story where forming a relationship with a certain character feels like reading a good book rather than getting to the next checkpoint in Super Mario.
Romances should be the ending branch of a NPCs character, the optional finishing touch to the relationship between the PC and the character in question.
