Basically I just really appreciated mrbluesky 's FE:Awakening guide and thought I should use my ~japanese skillz~ to help others or w/e (also I'm really lonely with nobody to talk to until 2016 about FE.....so.......). This is written assuming you've played Awakening so I might gloss over some of the super basics
These will not contain any spoilers (most of the time I won't even be mentioning characters by their names or any specifics, except for the main character and Aqua/Azura ie "the blue girl", up until the section on the kids). At the end I'll have some opinions on "smart strategic choices" that will mention characters, but that will be clearly marked. Also note that I have only played the Nohr version (I'm planning on getting Hoshido/3rd route in English) and so this will be very Nohr-centric.
Also this isn't meant to be the Best guide and there could be a lot more improvements I'm just... writing out a lot of stuff I wish I knew when I started, and this is more for people who are just starting out
