King's Quest

King's Quest was the first game in the King's Quest series.  It was also the first game to use Sierra's AGI engine, which allowed the player to move the character throughout a scene and combined a text parser for actions, which was ground breaking at the time.  Sir Graham is chosen to find the three treasures of Daventry. Once he finds them, he shall become king.

The game was released in 1983 as a keyboard controlled graphical adventure game with a text parser using Sierra's AGI engine.  In 1990, it was remade as a point-and-click adventure game with remade art in 256 colors using Sierra's SCI engine.

Both the original AGI version and the SCI remake of King's Quest are now supported by ScummVM, a program designed to let 2D adventure games run on multiple platforms. With ScummVM, King's Quest now runs on modern versions of windows, as well as Linux, Mac OS X, and many consoles such as Dreamcast, Wii, PlayStation 2, and PlayStation Portable.
