Actually I'm not all the bothered about romances of any kind in the game. What I would really like are some options to develop strong friendships. This isn't done enough in games.

The friendship with Morrigan in Dragon Age Origins if you are playing a female character. Its touching, Morrigan opens up that you are the first friend she has ever had, etc.

Can't think of any other examples at the moment but something where you become friends and perhaps influence the NPC in some way (bringing Shadowheart to the light side? I hope that doesn't require a romance).
