I see, thank you for all your help, good sir.
A few more questions:
How do I build the more advanced buildings (like Brewery instead of Distellery?)
What does Magic do?
Magic is very complicated to explain. I also haven't messed with it very much. I'm more of a steel against flesh kind of overlord. I'd suggest reading through the magic portion of the manual closely. But as you are starting out I'd suggest avoiding fire magic until you know what you are doing. The ranged magic users don't have friendly fire off haha.
As for your brewery go into build and workshops like you normally would. The list will be much longer in there. Scroll down until you see Brewery and build it. If you don't have all the materials available in the top right will pop up in red whatever is necessary that you don't have. Most likely for brewery you will be short on empty barrels.
Also we have veered off topic. There is actually a thread usually on the first or second page about gameplay questions. Most of your basic ones should go into DWARF. There is also an ORC one for ORC specific gameplay tips and using their unique buildings. You can go in each thread and use the search function at the top to find most of these already answered.
The main part is spend some time in that manual. It's very well written and gives quite a few hints. Start out learning the basics of new workshops. You won't really hit magic until your fortress is rather mature since it require platinum and other reagents.
It may also be worth your time to check through the random threads here. You'll find several good reads in forts people are making and youtube let's play videos. Both entertaining and educational.
