I didn't know where to ask this one, but are you going to be bringing back the mature themes from the earlier games?
Fallout 1 and 2 contained a number of mature sexual themes. You could save a prostitute's life in F1, and in F2 you could get married, become a porn star, and hire prostitutes. I liked the way this was handled in the past (cutting away to a black screen to insinuate something occured) so I'm not really expecting porn here.
What worries me is that I was surprised by a lack of anything along these lines in Fallout 3. Sex in any form was just missing from the savage struggle for human survival. There weren't even any hints at romantic subplots. The closest we got to that was Bittercup in Bigtown, who'd hint that she liked your chacter and that's it. It seems like they decided to just dump any sexual/romantic content & themes and pretended it didn't exist. There's a lone prostitute in Megaton who will go lie in a bed for money, that's it. Even Fable was a bit more risque then that!
It's not an odd request though. Sex has always been a part of the post-apoc genre. Saving gals, finding love, finding sex (a boy and his dog?), and etc... But it helps lend some more humanity to the game and it's something I always came to expect from Fallout.
So, is there any chance that Obsidian's going to bring back those mature themes, or will we be stuck with the same, bland, violence focus that we saw in Fallout 3?
