I should try this game again. I tried picking it up last summer. I embarked to a region that had a nice range of trees, cliffs and water (with the possibility of some magma). Of course, I get there, and it's completely different from what I thought it was. I'm in a barren wasteland of rock salt. About 10 z-levels down there's an outcropping in the cliff that is slightly forested. The water is a seasonal lake on some other little ledge. I start digging a hole in the side of the mountain. It took too long and I gave up, I hope the stupid dwarves enjoy salt beds and doors made of salt.
I had a bit more luck in adventure mode, throwing pebbles, bones, rocks, worms and severed limbs at my foes.
Even if I still don't get the fortress mode this time around I'm sure I've figured out adventure mode pretty well.
I'm going to go generate a world or two now. I figure I'll make a tiny world for adventure mode.
