I started up a game of 40d Dig Deeper.
Semi-randomly (didn't use finder) found myself a nice embark on a forked river which turned out to be really sweet.
Decided to build a half-above half-below fortress/castle against the river. Things went pretty well to start, well, that is except for my expedition leader/bookkeeper/miner falling into the river after a small cave in... and my axedwarf/wood cutter fell into the river while chasing geese... But, I mean, other than that things were going well and got better when I got a huge immigration wave taking me from 5 to 27 dwarves in one pop.
Everyone got integrated into my fort quickly and well. Things were really working out when my first orc siege showed up. I had a small military of four legendary wrestlers that only just got equipped with steel axes and steel chainmail moments before, but no trained archers other than a hunter and no siege engines or engineers up and running. So I shut myself in.
I don't like playing with traps or deathworks much, since it makes the game entirely too easy. So I initiated a plan to get a siege engine in place to fire on the orcs. I would open and close a bridge to lure the orcs closer, and ultimately into the line of fire of my newly built catapult range (minus the actual catapult, at that point... but it was coming). Making the range was a rush too, since I had to breach a sheer dirt wall and quickly build a stone wall in its place which could then be carved into fortifications.
But as things always seem to when I try to be smart, something went wrong. In order to lure the orcs into a safe position that I could fire on, I had to open/close my sally gate. The sally gate happened to be located right next to the lever room and was pretty much next to the heart of my fort. Naturally during one of my lever pull orders a dwarf on the other side of the known universe was selected for the job. So while he slowly meandered his way towards the lever to close the frighteningly wide open gate, the orcs happily rushed towards my fort. Realizing that they were close enough that even should the lever be pulled, they'd probably access my fort I went into panic mode and started ordering walls to block access to other parts of my fort... Unfortunately, as I pointed out before the sally gate was essentially connected to the heart of my fort, which made for sealing the area off near impossible.
In the orcs came, killing my feeble military with ease and slaughtering my civilians with joy. In the hectic commotion the lever DID get pulled, which ultimately cut off escape from the rampaging orcs, now sealed in my fort.
After much death and destruction I was able to get several (read: 4) dwarves to the surface where they walled off the two 'down' access points.
The surface had a small wood stockpile, two larger stone stockpiles, several workshops, but no other supplies. All the food, tools, weapons, armor, etc. were down below, being sampled by the orcs. The 4 dwarves had access to drinking water and fishable pools, though. After a while, the orcs decided my fort wasn't all that great and called off the siege... but were still sealed in. I came up with a plan to breach one of my down access points and quickly seal off the room it accessed. That room contained two dead bodies (an orc and one of my military) with metal on their corpses. I would then melt down the metal and make a pick. With the pick I'd dig a tunnel from the river and flood my fortress. Teach those fucking orcs whose boss. It was a great plan.
Except... as soon as I breached the down stair, my dwarves bum rushed the supply stockpile for food... despite the fact the orcs were standing on it. This led to a ridiculously long period of my four dwarves trying to get to the food or beds (despite it all being forbidden) but just getting interrupted and scared back by the orcs, only to repeat the process a moment later. The orcs, for some reason, were content watching my dwarves run back and forth like idiots and didn't engage them (I guess they were just trying to path out of the fortress, since the siege was over). Finally, after a heck of long time one of the dwarves managed to grab a bite to eat of some forbidden food, which gave him the will power to actually build the wall I wanted them to long before. At some point in the process two of the 4 dwarves got themselves killed and the other was ultimately walled in with the orcs.
So I was left with one 'safe' Dwarf. He then had access to the farm plot which awesomely had plants growing, which he was able to eat and the bodies with metal on them. He managed to melt down some steel and finally got a bar which he was able to make a pick out of.
Then I left to see the midnight showing of Iron Man 2.
So now, when I get home tonight, I will task my lone surviving dwarf (his buddy inside starved to death) with digging a water tunnel into my fort to drown the orcs. Then it will be a simple mater of building a pump or two to de-flood the fort (thank god I door off my rooms and stairwells... only a few are propped open) and start burials.
I hope this guy doesn't mind being alone for a bit...
