Best.
Thing.
Ever.
I remember that thread, holy stuff it was awesome.
Sounds fun, count me in.
Don't worry, I won't KILL the dwarves. Just set traps everywhere and make the fortress untouchable. :D
actually you know that may kill dwarves too
Traps don't trigger when dwarves step on them (except the Spike traps). And yes, traps are insanely useful when it comes to defending the fort.
Traps will target only hostiles, like beserk dwarves and crazy animals. Traps are not triggered by the run-of-the-mill kobold thief, but ARE triggered by goblin babysnatchers and Master Thiefs.
Edit: Also, Cage traps are the current golden-gun of the game, they can catch absolutely anything apparently, even Megabeasts like dragons and titans, then you can tame those megabeasts (yes, you can own them!) and have them roam your fort.
