When a degree of randomness and unpredictability is added to the game so that we get some random traffic past our fortress rather than just having scripted caravans and attacks arriving on a fixed time schedule, Trojan traders would be awesome.
Come on, imagine not knowing about it and having it happen to you for the first time!
:looking at idling wood furnance:"Dangit, outta wood, gotta get some trees cut... wait, what's this?
:drops axe and runs over to computer: Wandering human traders visiting my DF fort, superb, hope they brought lotsa cheese!"
:orders broker to get to depot and selects some surplus goods to be dropped off for trading while making sure the on-duty military and lookouts are armed and ready up on the walls:"Great, here they come rolling in, safely at the depot. And there the drawbridge is shut behind them. I think that unless they bring some really neat stuff I'll hold off trading the gold stuff, I'll save that for the annual dwarven caravan and their steel--
An ambush! Curse them!I knew it! Been a while since those brigands made an attack attempt! Now let's see, where are they, at least those slow pokes decided to spring the ambush

:hits 'U' key, goes to "Hostiles" tab, tells game to zooms on first Human brigand on list, and watches the paused image...:...
... !!! ... oh. Oh. Oh!
Holy Armok-****ing
#ق€@Җ!, HEEELP!:Cue panic and frantic scrambling of troops as the poor broker and hauler start running in terror away from the trade depot:
Edit: of course you'd need some kind of preventive measure for this, such as the ability to let your guards search the caravan crew and holding on to their weapons while they're inside.
