As stated in title. Decided I should get back into the game, and looking a bit over the learning/writing/thinking system, as well as the taverns, and how to make it the most... scientific~. Anyone have suggestions/challenges?
To create an inn, you should have a dining hall, so literally just a table. You can also place a meeting zone and assign it to a tavern or inn. Libraries can be created in the exact same way, but you are encouraged to have some bookcases, chests, and of course tables and chairs so dwarves can sit down and read comfortably (but dwarves will also stand and read books).
In general you'll attract a lot of visitors, generally bards, mercenaries, and so on to taverns, or you can attract scholars to libraries, but that's just a generalisation. If you want a multi-racial fort you need to have one or the other. In Firecastle, a succession game that started recently, I started to get residency petitions close to the end of the first year, so you can actually expand your population quite quickly.
It takes a few years after that to get a citizenship petition, and once you get that the residents can be assigned labours like other dwarfs.
The fact is the mercenaries hang around the tavern, and I think you can actually make a barracks part of the tavern (since it technically is a bedroom; I know I managed to make a dormitory part of a library in Firecastle early on). This means you can strategically place your taverns where the mercenaries will actually play a useful defence role.
There's a lot of research that can be done in a library and you can probably collect a lot of books there by buying them off caravans to get through the tech tree. You can also put necromancer's books in the library and the dwarves reading them will learn necromancy.
