"Oh, look, a new version of Dwarf Fortress. Let me see what's in it."
"Oh, look, a necromancer siege. That's a lot of zombies. I think I'll just wall my dwarves in until the pit trap is operational."
"Oh, look, there goblins ambushing...the zombie horde. That should go well."
"Were there always that many zombie goblins outside?"
"Oh, look, a named dragon has appeared. Maybe he'll break the zombie siege."
"Oh, look, about 120 zombies trump one dragon. But the wildfires he started are taking out a lot of the horde."
"Oh, look, it's raining human blood. At least that'll put out some of the wildfires."
"Yay, the pit trap is done! Invite the zombies into it!"
"Oh, look, falling 20 z-levels doesn't kill zombies unless they land on their head. That's...unusually unrealistic for DF."
"Okay, I have a mostly untrained squad in full steel armor, let's see what they can do with the zombies. I'll back them up with serrated steel traps just in case."
"Oh, look, I didn't know that necromancers could turn dragons into zombies."
"Oh, look -- away from the blood-soaked plain littered with charred and severed zombie parts, along a trail composed of bits of steel armor and the shreds of my untrained squad, there are chunks of zombie dragon cut into fine giblets at the entrance to my fort."
So let's review. Goblins < Dragon < Zombies < Steel-clad dwarves < Zombie Dragons < Serrated steel blade traps.
Now I'm dealing with, "Oh, look at all the ghosts."
