I've always liked FTA simply because there is adventure here and bucket loads of it. Both books are crammed with adventure hooks, high intrigue, mystery and wonder. The post war Greyhawk setting is a dangerous place but is somewhere that adventurous souls can really make a difference.
The new (2014) scans clock in at a mighty 144mb but the quality is greatly improved over the previous versions. The text is much clearer and easy to read and the maps are no longer cut up and spread over several pages of the PDF.
