I started playing fortress mode as my adventurer broke with the update. My first fortress starved, the second got slaughtered by a giant bat, the third I abandoned because absolutely no immigrants came. My current fortress is basically a small castle, with half the stuff being underground. Two dwarves died in accidents. One dwarf was so sad about the second one that he spent days sitting at the river staring into the water. And right now I'm waiting out a tiny gobling siege as I have no soldiers yet.
I can't wait for more immigrants, forcing me to expand into the glorious lands of infinite fun.
