The original game was released in 1983 on both the Commodore 64, and Atari 8-bit computers. You are an archer, restricted to the bottom of the screen, and tasked with hunting monsters. As the game progresses the time changes from day to night.
The sequel was released in 1985, this time only on the C64. It added multiple locations, and the abilities to walk 'into' the map—scaling the sprite as players did so. It sounds amazing, and mechanically and visually it is beautiful and clunky in a particularly videogamey way.
The 2003 iteration was released for PC, this time in full 3-D. The game is played from a third-person perspective, but hanged to first-person when aiming and firing the game's only weapon; the bow. It seems to be missing all the the terrific graphics and music of its predecessors; it's about as charming as a homebrew N64 game.
