While I do admire and encourage your enthusiastic slaughter of a skulking race, I have a few things to say:
1.) I will ensure that you never learn who I am or where I live, as I am less like Rihanna and more like her ancestors when it comes to whips and chains.
2.) You still didn't answer my question: while you obviously love to torture the kobolds, why not add Goblin Claus simply for the sake of including him in your festivities? I'm quite certain he'll feel left out if you don't.
I am not Rihanna, nor do I share her... fetishes.
I'm not saying that I would refrain from killing goblins, after all Armok demands blood and who am I to deny it? There's just no real satisfaction in it. They're brutish, ugly, evil creatures who go on the offensive and attack dwarves for the hell of it. Kobolds on the other hand are small, defenseless creatures who only attack when they're cornered and are forced to put their lives on the line and steal just to survive.
I can only laugh maniacally after the mass slaughter of one of those two.
But... Armok DEMANDS that there is NO end to the slaughter! While your preference for 'prey' that actually resists makes sense in a predatory mindset, remember that what the greenskins lack in reluctance they compensate for in sheer numbers (and liters of blood for donation to Armok's dinner table). However if you 'feed' the mongrels enough to encourage a full-out assault you may be able to appease his bloodlust for a short time... but I have not been able to recreate that scenario since my first fortress attempt, and even then from what I now know that still is not enough to sate His thirst.
That being said
please continue with your butchery as it reminds those of non-dwarven heritage that we are not to be trifled with, and to do so anyway results in their undoing.
And @wierd, what was it Einstein said? A little knowledge is a dangerous thing, but so is a lot? Or is that just from Eureka? (either way, it tells scores about our dwarven charges)
And again @Kodkod, I am both fearful and intrigued by your retribution against your former fiancee and potential mate. Did it involve magma like a true dwarven undertaking (literally or figuratively) or was of a more Human or even (bleh) Elven nature?
