Baldur's Gate is a fantasy role-playing video game developed by BioWare and published in 1998 by Interplay Entertainment. It is the first game in the Baldur's Gate series and takes place in the Forgotten Realms, a high fantasy campaign setting, using a modified version of the Advanced Dungeons & Dragons (AD&D) 2nd edition rules. It was the first game to use the Infinity Engine for its graphics, with Interplay using the engine for other Forgotten Realms-licensed games, including the Icewind Dale series, as well as other licensed D&D campaign worlds such as Planescape: Torment. The game's story focuses on players controlling a protagonist of their own creation who finds themselves travelling across the Sword Coast alongside a party of companions, to unravel the mystery surrounding a sudden iron crisis affecting the region and attempting to discover the culprits behind it, all while uncovering dark secrets about their origins and dealing with attempts on their life.
