I'm not too keen on this idea, mainly because it
puts an unequal burden on femals PCs that male PCs won't have. Unless there is another similar situation to Kirkwall where you have (1) a time lapse of several years; (2) a stable, permanent house to live in [ie NOT party camp as in DAO]; (3) a period of relative safety for about 6 months [this includes the latter part of pregnancy and the first few baby months] I don't see how it's doable.
We are supposed to be adventurers: putting ourselves in dangerous situations, kicking ass, wreaking havoc on baddies, and drawing the wrath and ire of our enemies. You think I want to deal with a pregnant PC doing all of that?
And too, how would you make it
optional? Through a convoluted series of dialogues that may or may not be vague, trying to guess the female PC's reaction to becoming pregnant? What if I'm dense, or just don't think it's a possibility in this game and answer positively in thinking of a
future scenario with my LI, not knowing it will influence my current game? Do you know how utterly PISSED OFF I would be? The other option is of course to directly ask the player through dialogue options, but that seems lame and gamey, and Bioware doesn't even want to add a toggle for sexual preference, so I doubt they would add it for child bearing.
The only way to do this and keep it equal would be to have a situation where the PC, male or female, is starting out with a family, possibly including children that would be out of infancy. At that point, the parent could leave (sadly and all that) because of some prophecy, encroaching danger, being in the right place at the wrong time to help so-and-so NPC, be captured by whoever bad guy, and so forth.
I'll add though that being a parent takes away a tremendous amount of RP from the player, being even less of a blank slate than Hawke or Cousland Warden was. It ascribes a really serious set of goals and motivations that you might not have otherwise because you know you have to make it through this fight, and the next fight, and the fight after that alive
so you can get back to your children. It also forces on you the desire of wanting to save the world in order to save your children -- which I find lame -- when really, saving it for yourself should be enough.
Finally, I do not want children hanging around in my game. I don't like children, and they are presented as annoying in movies/TV, or are all written with the same tropes: bratty/angry with the world/self absorbed teen, precocious/clever/wise beyond years younger child, or the awkward/geeky tween -- one of the few shows where I liked all of the children was
Terra Nova. I don't even like quests involving children, part of which has to do with the devs making them look odd, or having only 2-3 models of each gender all in the same age-range, so you have a bunch of clones running around. I saw several Amalia's and the kid next to Chanter Devons throughout DAO.
