One version is common, at least one other version is rare
 Based on the classic strategy text "The Art of War", written by Sun Tzu circa 400 B.C.
 Game includes Amiga reference docs on-disk (see "ReadMe.txt" on disk 1) and a built-in campaign editor. Additionally, the game supports different keymaps (to change from the GB default refer to "ReadMe.txt" on disk 1), savegames and PAL/NTSC screenmodes.
 The NTSC version of ANCIENT ART OF WAR IN THE SKIES may be activated by double-clicking the "60Hz Screen Stretcher" icon on disk 1, but publisher MicroProse warned in the on-disk docs that this software solution may not work on all Amiga set-ups and might require the ECS chipset and a monitor.
 According to the on-disk docs, the "Game Options" clipboard in-game displays an option to turn off the joystick. However, clicking on it doesn't do anything as it is a leftover option from the original PC version that wasn't removed.
