If you're going to present the player with realistic characters, romance should probably be part of the equation.
That goes double if you're BioWare, and you pride yourself on creating likable, even memorable characters.
However, romance in games can often lead to problems (as the fans well know), and one of those fans asked Dragon Age lead writer David Gaider if the team had considered ditching romantic sub-plots. He responded as follows :
"To me, the thing that BioWare does best is not story but characters. I think our characters are done to a level that few other games even attempt, with an element of agency that strikes a chord in our players … and romances have been a natural outgrowth of that. Sure we could stop, but that would be turning our backs on something we do which almost no-one else does."
That all being said, Gaider added that romance could be sidelined in the future. He said that if they make a new IP, they may not want to "open that particular Pandora's Box," which makes sense. Still, it'd be something of a sacrifice, as he says some people really enjoy that part of their games, and they wouldn't like to see romance disappear. Added Gaider- "Some folks might be eager to write those fans off, but I'm not really sure that BioWare feels the same."
I'm still not sure why the concept of romance in games is so much more controversial than it is in other entertainment mediums. Must have something to do with the interactive nature of the hobby, huh?
