As awesome as the giant lions are, they catsplode.
A large breeding pop of them explode like fuzzy kittycats do. On the plus side: trainable for war, and no kittycat mind control.
The rate of production is ferocious though.
In 3 years I have gone from a single male and female giant lion, to 100 giant lions, and a combined creature population hitting the 300ish unit ceiling.
At least this has effectively neutered the kittycat reproduction cycle as well.
Either sadly, or delightfully, the giant lions produce epic crap-tons of meat. I am swimming in over 2000 meat, and the temporary construction pit fortress's food stockpile is literally overflowing.
I don't get migrants, because dwarves are nearly eextinct, and my population is a paltry 23 dwarves, of which several are children.
I am trying to get a massive local dwarven presense built up, along with a crazy wild megaproject. The lack of reinforcements and the tiny, vulnerable nature of the site has me with invaders off... so, I have this deadly killing force just laying around sunning themselves.
I nearly have the ground floor level of the megaproject completed, and am working on subfloor 1 with my 2 legendary miners, as well s cleaning out the central neck of the volcano.
It is my plan to release the fort as a community succession game focused entirely on carnage and horror, once the fortress has reached a stable and complete status. The world is brimming with savagery, which would seem to explain the elves bringing giant monsters in for trade, as well as several thriving goblin civs. As I said, no new migrants. I turned up the number of megabeasts and titans as well during worldgen. (It went through 2000 gen attempts before spitting out this world)
I am in the midst of landscaping the volcano so that the only land path to the front door will be easily defendable, but will purposefully leave it undefended, as I want to see what players will do with it.
The neck of the volcano is being widened to a nice, smoothed-wall shaft over 300 tiles wide on both sides, so a mechanically induced eruption with a central pumpstack should be a easy upgrade.
Did I mention it's in the middle of a dense forest, with the elves right next door?
(goblin fortress is nearby)
The world was genned for 1050 years. Currently on year 25 of construction.
When it's ready, I will present it.
