Yeah, I was thinking about the industry issue because now, apart from dwarf-power it's not a problem to do most industries. However, it's kind of against the flavour of the challenge. To be honest, the thread and cloth were just so I could get sutures and bandages, so I think that's *mostly* fair -- and it turns out that I have webs on the map as well.. I'm debating whether or not to try a raid. I don't actually mind if the ending of the campaign is due to uniform corruption. It seems non-deterministic and chancing your luck seems to be in keeping with the theme. Normally raiding to get junk is kind of silly, but in this case it might be useful. But with only 4 fighting dwarfs and no real possibility to get more in the short term... Probably not a good idea. I think your 2 waves of migrants is looking more and more like a good idea. Had I not been stupid about the crossbowman, I would have been in much better shape, though. The visitors basically run away when you attack them and only fight back when cornered. As long as you have a bit of fighting prowess you should be able to take on visitors 1 by 1, even without weapons because they tend not to have any skill.
Anyway, I'm going to add some more house rules to my personal challenge: no growing. We aren't farmers! Historically bandits were often people who specifically opted out of the farmer role ;-) Like you say, no clothes making. Dead man's apparel is fashionable! I think thread and cloth is OK to make for hospital use, as are splints and crutches. I'm now thinking the same thing for bone/shell carving and leather working for armour. You're a pretty sad bandit if you are spending your days making armour. On the other hand, doing some crafts to keep the dwarfs sane is important, so I think you can RP whatever crafting you want -- if it's a legitimate hobby, then so be it ;-) My own exception to no clothes making *might* be bags, just so I can dispose of seeds more easily (I suppose you could configure them out almost entirely, though).
Edit: Down to 3. The requirement to kill the outpost liason is *tough*. I recommend not having any visitors around when it happens. Also, the caravan parks at the edge of the map, so if you are feeling especially brave, you *can* try your luck with it. Without a way to replenish your ranks, I think you need to have a much more conservative approach. But if you like action, then this is quite fun. I think I'm probably done with it now, though ;-)
