I'd like to see an improvement in layout, or rather a facet of the book's layout. As it is now, HERO 5th stands out as a well-edited and nice book to read. I don't find the language particularly dry (maybe that's because I'm used to reading scientific papers on color reproduction and similar stuff), and the art is also good. BUT, there are virtually no margins. I understand that there's a lot of text that needs to get into as thin a book as possible, but I don't find that a good enough excuse for taking a nose-dive with this part of the layout. The margins of a page is not the space that is left after everything else has been put in. It's a form element like everything else (typeface, type size, leading, column size etc.) and it does affect readability, first impression and so on. I know I might come off as overly zealous about something that others might consider a minor issue (or none at all), but I've worked a bit with layout professionally and it annoys me when a game this good lacks a basic layout quality. Apart from the margins though, the game is well-made layout-wise.
Thanks for listening.
