Games like king's quest iii: to heir is human

King's Quest III: To Heir Is Human is the third installment in the King's Quest series of graphic adventure games developed and released by Sierra On-Line in 1986. The game was originally released for the Apple II and PC DOS, and later ported to several other computer systems. It was the first title game in the series not to feature King Graham as the player character.

Most of the game's various lands and locations appear in the magic map. Once the protagonist Gwydion reaches a new region, he can use the magic map to travel to a previous region.

King's Quest III was markedly more difficult than its two predecessors. The player was required to type in magic spells line-by-line from a spell book that came with the game. The spells partially served as a form of copy protection, although the game already had a disk-based protection (it ran on a self-booter required disks to play, and could not be copied easily).
