546 pages. That is a book. What was the book about? Gameplay? dev stuff?
All the above, plus a synopsis of the largest squadrons at the time, WWII pilot stories, a break down of each aircraft, tactics/tips, history of the game from AirWarrior to Warbirds in 1999 (including the resignation of HiTech and staff from IMagic to form HiTech Creations), the Warbirds community in various countries, Warbirds events, etc.
Great bit of history filling in the AirWarrior to Aces High progress and how much Dale has contributed to the genre.
