Betrayal at Krondor is an MS-DOS-based RPG taking place largely in Midkemia, the fantasy world developed by Raymond E. Feist in his Riftwar novels. The game is designed to resemble a book, separated into chapters and narrated in the third-person with a quick-save bookmark feature. Gameplay occurs mainly from a first-person perspective while traveling the overworld, dungeons, and caves, but switches to a third-person view during combat. The user interface is mouse-driven, with keyboard hotkeys for each action. The game runs in 256-color 320x200 VGA mode. The graphics engine uses textured 3D graphics to draw the terrain and uses sprites for most of the detailed objects. Sales of the original 3½" floppy disk release were slow, leading Sierra to sell the Riftwar rights back to Raymond Feist, but the game became a hit when it was re-released on CD-ROM.
