Well there are no rationale per se in arranging the buildings in such a way in the file. I'm basically using the building list (excel sheet) uploaded by Alex Rockwell and presented it in a colorful format. Credit goes to Alex for taking time to put up the file.
Maybe I can update the file and rearrange it in the order you suggested, I think it will be logical when playing the game. This is my first attempt doing this, pls don't be harsh on me...
Thank you for preserving the Illustrator editing capability of the PDF file. My aging eyes struggled with the 6 pt type, however, with the preserved editing capability I was able to convert it into a single full page portrait chart with 9 pt type in less than a minute.
