Okay, I feel kind of odd even having any complaints here. I mean, it's only $2, and for that price it's a great deal regardless.
I like the concept, having a journal or sketchbook for dungeons fits how I tend to create, so this was a good fit for me. The tables and creative cues are a nice touch. However, losing a section of almost every page to the little tables and cues is frustrating. It effectively makes a section of the page unusable for dungeon design, and forces you to flip back and forth to look at them all. I would have preferred that those had their own pages and that more of the design grid pages had been kept clean for use. Out of 60 pages, only 4 are kept clear for a nice two page spread.
Mind, if you're going to print these out and I would guess that most would, you can fix this yourself by just printing more of those pages... Maybe at some point I will see if I can reassemble this for my own use on an 11x17 page layout to make a saddle stitched booklet possible. A little more work on my end, but as I said, this is only $2.
Hence 4 out of 5.
