I'd love to fill these with art. But every 2 B&W portraits or 1 B&W mech illo adds $1 to the price, which drives it outside the scope of the line. Secondly, art heavily a drags down production time and part of the goal here is to reproduce cool, light books to add to the universe while not bogging down production on this line or competing for resources on larger projects. Lastly, consistency—we want to make sure the content (and price) on these is fairly consistent, though in the future we may see Brent, myself or some of the writers contribute "bonus" content in the way of art, fluff or record sheets/cards/data (without impacting price or production time). Time will tell.
I realize that you know this "more or less," but just wanted to be transparent.
Now, to immediately do a 180 on everything I just said, in two weeks we'll be releasing a special bonus sized Touring the Stars for a slight markup, with double to triple the content. More on that later—it should be a ton of fun. :)
