A 40.19 - 40.22 fort, I think I was six or seven years in, no fights other than a random giantess, which upset all the thirty wrestlers who near-instantly killed her. Upgrade to .23 there was immediately a goblin siege, which I had to lock out because the wee dears had become accustomed to peace. They wandered off not long after all my animals had to be butchered to stop them starving (plus, I needed food).
The dorf caravan came, winter freeze happened, widened my aquifer punch a bit (stupid 2-layer aquifer under 1-layer soil), and then some bandits, humans and dwarves, mostly, hilariously even ... well, spoilers. Anyway, the combat speed thing is terrifying, enemies jumping over rivers and climbing walls and whatnot, all at about 4-5 ticks per step. These ones are being persistent, booze is gone, food is scarce, so I'm arming up as well as I can and trying to split them up and pick them off, which pretty much works. Aside from how their leader blocked the first thirty attacks while hacking up three dorfs and only a lucky headshot with a =steel spear=, followed by a copper pick splitting his skull like a ripe melon ... which of course upset all the rookies, which is everyone. Punching people in armour does not work.
Glad I melted the spare anvil for that spear though. Really need to stop messing around and get a defence up. If only the deep ore had been something other than Sphalerite. I hope the mountainhome likes goblets, because importing steel is expensive, and this river kills far more fishermen than it's worth to fish for shellgoods. Not to mention the giant ravens, which never seem to turn up when there's a siege on. And of course all the forgotten beasts roaming the caverns have webs or worse.
Hey, at least there's a magma tube, which I should really get on and tap.
