Icewind Dale is a role-playing video game developed by Black Isle Studios and originally published by Interplay Entertainment for Windows in 2000 and by MacPlay for the Macintosh in 2002 (both the Classic Mac OS and OS X). The game takes place in the "Dungeons & Dragons" Forgotten Realms campaign setting and the region of Icewind Dale, and utilises the 2nd edition ruleset. The story follows a different set of events than those of R. A. Salvatore's "The Icewind Dale Trilogy" novels: in the game, an adventuring party becomes enlisted as a caravan guard while in Icewind Dale, in the wake of strange events, and eventually discover a plot that threatens the Ten Towns of Icewind Dale and beyond.
