772 pages(!) covering almost every graphic adventure that you might want to play as an adult. 

My only complaint is that there aren't any internal links within the PDF, so you have to navigate within it the slow way or via searching for text.

(Oh, and the EGA version of The Secret of Monkey Island had one big problem: thanks to the 16 colour limitation, the text of the disguised clue texts like the dance routine is unreadable, so you have to resort to guess work. I got sent a free VGA copy when I complained about this...)
