Since we are all noobs (including me, I have forgotten most everything from this game) I'd suggest that we use the LNP feature to DISABLE aquifers. Aquifers are generally a pain in the fucking ass to handle, I'd rather just undermine a pond and use that for water (or use a underground river, but that's beyond the point). Also, I can not play without a texture pack, DF ASCII is way too fucking messy.
I agree with all the points you make. I had completely forgotten that LNP lets you disable aquifers. AND it is fortunate that the LNP lets you effortlessly use any texture pack you want, and will even convert the raws of a save file, just in case you don't like the texture pack your peers are using.
In other dorf stuff, I havn't touched adventure mode in ages. I completely forgot about the market NPCs hocking their goods at you. My personal favorite; "YOUR VERY OWN CELERY! LIMITED SUPPLY!" Like it's some kind of rare thing that everyone wants. "Don't you want this celery? Don't you know? Celery is all the rage!" While filthy human hipsters run around the villages proclaiming loudly "I was into celery before it was cool!" and then that goblin threw me down the well.
Aaaand, one of the new things you can do in adventure mode is to write poems. The poetic styles (also musical styles) are randomly generated when the world is genned. I was looking through the styles I could choose to compose my first poem and noticed one called "the dead dusts." I looked over it's description and the style is basically the way one performs a standard three card tarot reading, except that this poetry style is mostly used to emphasize various aspects of death.
