Just started Adventuring this world; very fun! After some random deaths to wildlife then demons, I started scumming to enjoy it a bit more.
I'd suggest a few things to streamline this a bit more. Some sort of walkthrough for dungeon designers and such so it's easier to understand with a small FAQ on why some errors may come up. I'd also suggest any designers to use Dwarf Companion and other utilities to make their dwarves Legendary in everything and use reveal to make planning easier.
Having duplicate raws for "normal" and "design" modes so people can easily switch between. The default would be "normal", of course. Also, I think it'd be neat as a 'tradition' for designers to make their own Adventurer after they complete their fort. A few rules would be no exploits, savescumming or 'training' with endless throwing, sneaking, swimming, etc. Basically, they make an Adventurer with their name and strike out... see how long they live as the world progresses between each person. Another 'tradition' would be to allow forts to leave behind only one artifact/adamantine equipment; allowing players to collect a 'set' after visiting each. This can be done easily with utilities to force strange moods on any dwarf chosen.
Also, not sure where I read it but it would be very neat to have basic introductions to the dungeons and such.
Some tips that are useful:
Adventurers, try to clear out the area of hostiles before trying to take on the fort. Nothing more annoying than getting wrestled whilst a chamber fills with water and you die from hugging a ratman. Also, use the 'l'ook feature on doors, floodgates, hatches, bridges, etc for mechanisms. That's usually a sign for something scary. Also, never trust locked doors. Or doors in general.
Designers, don't be afraid to make "dummy" levers. Hook up a lever to a bridge then dismantle the bridge. The lever will still have that extra mechanism to be tricky. I believe hatches are unseen when used as ceiling while underground in Adventurer mode. In a certain fort,
I pulled a lever which opened hatches above and proceeded to drown me.
Even though I was using 'l'ook a lot and consistently switching Z-levels, they didn't show up.
Also, I recommend Designers atomsmash or chasm any leftovers not intended. Definitely dismantle any buildings and such that aren't intended. There was a few forts with tons of stone clutter.. kind of ruins it as I'm constantly thinking "Oh god! Where's the 1 tile garbage zone?!' The rampant stones also tend to cover up whatever may be on the ground.
Anyway, been quite fun discovering things.
