Bill Owen wrote in Bill Owen Q&A:Back to Tractics...I wrote that when I THOUGHT I was nearly done. I found out that Mike Reese kept thinking of new things to add or old things to fine-tune. So we finally got to print in December of 2021. We have eight identical print editions, which only vary by binding (softcover, coil binding, and hardcover), black ink interior pages for economy or full color, and "view" of the 45 pages of game reference charts: Landscape or Portrait.Then last month, we came up with a PDF version of Tractics. This was in the place of the Kindle edition that proved to be just too difficult for me to master. Has hundreds of hyperlinks within the PDF to teleport to relevant sections.
