Yes I have taken lots of notes for things in the game. but they dont' look as neat and tidy as yours! I just need to sometimes when I'm trying to accomplish a goal and for a game like this it takes awhile since there's so much multi-tasking.
Gosh you have nice handwriting. Always feel jealous of people like you because mine is atrocious (sometimes I can't even read what I wrote myself!). As for taking notes on the game, I haven't yet but always kind of wanted to grab a notebook and head to the wiki. I hate having to tab-out of games to look at a wiki, so just being able to pause and look up something in my own self-organized handbook would be great. I put the game down for a while, but now that I've got the itch to pick it back up soon (either with mods or update 1.1) maybe I should go ahead and do that to prepare.
I did loads of research on the wiki, and made a checklist of foods that were used in cooking recipes.
