I distinctly remember not being able to coast by with auto battle, so I have a couple of questions:
Which Culture Developments should I work on?

Also, how does the item system work? What's the best equipment for each character? How do I farm for good equipment?
Lastly, is there a walkthrough/guide I could use within this thread?
