so wait, my turn has been supersceded? blarg, oh well, i was taking a while. and just when i figured out using map reveal would stop all the annoying "you have struck uselessite" messages which had delayed me.
i was conisdering doing a completely stupid hand drawn and caligraphy catalogue of all the forts waaayyyyy back when this thread first started, and i was unemployed, miserable, and looking for something to do that would fill the endless time i had and recapture the feeling of some of the artsy things i used to do as a teenager (i did a bunch of illustrated kids books that i allways intended to polish up for publishing but never ever did. they are long gone now) at the time such a project was well within my power, but this thread has been such slow going with all the forts taking so long to appear that life went on for me, and now as i have a job and do a whole lot more socializing i have nowhere near the time.
if sausage isnt too far into his turn i can post my save with my incomplete fort and he can use that world, i have a LOT of digging done and some huge hollowed out areas inside the mountains, as in, 30 z levels of empty with a chasm at the bottom and little bridges here and there, which currently lead to nowhere. if hes well into something then dont worry, ive figured out how to do fast projects of that size now without the message slowdown, and i did all the difficult experimentation and planning. if the site is still free in a few turns time i can do it again in a more timely manner.
its very easy to create caveins for adventure mode. you can even make areas that can only be accessed through caveins making holes in the floor which you need to jump into. all you need is a section of stone which is only held up with supports, and that those supports are linked to a lever. removing the supports causes the stone to fall. instant cavein. i think that supports made of non magma safe material will collapse if exposed to magma, so there is another option for you right there. i havent personally tested this, but aparently large solid sections of rock can survive falling with internal passages intact, but everyting inside dies. be careful not to create a scenario where an adventurer can possibly change the landscape so they get trapped somewhere stupid, especially in your reward room. that would be very frustating.
as i said before in previous posts, the tweak utility works in DF 40d, you can give yourself 50 starting dwarves and enough steel bars on embark to create a metal techno tower of doom without needing to even dig. after you embark you can stick your save back into a 40d11 version. and adding the tag [SPEED:1] to dwarves makes them super duper fast. so things get done really quick.
good luck there sausage. may you create awesomeness.
