I'm not sure if this is a sign that there may be something wrong with me, but that actually sounds really nice.
Naw, just sounds like you're an introvert who needs a break. Take it from me: A couple weeks without other people jabbering at you can be a real vacation.
Do goblins breed? Catch another opposite-sex goblin and wall them in together... watch as dozens and dozens of goblins are forced to spend all their time in the same two-tile space...
You would and up breeding super-goblins that way, as they would fight and only the strong would survive. ![Wink ;)](http://97.107.128.126/smf/Smileys/aaron/wink.gif)
That would only work if goblins inherit things from their parents... And anyway, they could only access information from the first two goblins; so you'd end up with no better than the sum of the best the original two could muster, and probably less.
DF with genetics would be cool, though. I mean, it would actually make children non-annoying. Say Daddy's a natural blacksmith and Mommy's an axedwarf (who somehow didn't manage to get Baby skewered in battle)... Bet their kid would inherit something from them. Strength, I think, useful for both things? And it wouldn't be a huge drain on anything, anyway; all you'd need to do is store parents' stats in the kid's data, simple recessive/dominant structure. Don't need any of that real-life partial-dominance and epigenetics stuff; if The Sims 2 did without it, why not Dwarf Fortress?
