Phillip Hall was not the only designer of BlueMax. Their is another John Harshman.

John's actual position was the Developer. He was my contact at GDW if I had questions of them or if they had questions of me and I kept him advised of how far along I was on the game. Interestingly there was a bit of a problem with the second edition of the game. I saw it on the shelves of the local game store and called John to tell him I liked the new box. A few days later I got a call from Marc Miller. "Ummm, errr, ummm, it seems we never bought the game from you so you still own it. We'd like to continue paying royalties under the same agreement as the first printing if that's o.k.? I agreed and kept ownership of the game. When I finally got a copy and read the rules I found several errors, the most egregious being referencing the forward arc diagram as the firing "arc" even though they had printed the firing arc diagram calling it the Range Diagram. When the miniature version was printed we kept to the same deal. The miniature version also credits Alan Wright as the designer. Alan did all the early war aircraft and receiced co-billing as designer. I believe his pay was a dozen games, which was GDW's standard "pay" for people who added on to one of their games. All those folks who wrote articles and entire books for their miniature or role playing games got the ego boost of having their name on a published book and a dozen copies of their accomplishment. When GDW closed Frank Chadwick was kind enough to transfer all rights, such as artwork and design layout, to me. So the game is all mine now, Lock Stock and Barrel.
