NOT VALID ANYMORE
The save game files of CKII are not in plain text anymore - you can't just edit them with a text editor!
Badly needed update
After flexing my google-fu I came up pretty empty as far as descriptions of the structure of ck2 save games. This wiki page is the best thing I found and it feels like it is missing a lot. The player info section is really needed and currently is blank. I just got ck2 a week ago so I'm trying to learn as much I can. Are there other resources that I haven't found that could describe the save file structure better? I would be up for updating this wiki page with whatever I learn.
