I had a great Fortress, it could survive a pretty harsh invasion, mainly thanks to the fuckton of traps at the entrance. I left the last few goblins that were either injured or separated to get massacred by my Military dorfs. Good training. But, when I finally got down to the magma sea, I carelessly got both of my Miner dorfs burnt in the lava. > After assigning a couple of random dorfs to mining, I got so annoyed/sad at their disappointing mining rate, that the fun went away. I should probably go back to it and fix things up, but maybe some other time.
Oh, and, I sucked with mega-beasts. Every time one came from one of the 3 caves I'd encountered, I'd just leave them alone, and they'd go away. :3
