Icewind Dale

Icewind Dale is a sister game series to Baldur's Gate and Planescape: Torment, which was developed by Black Ilse Studios.

Unlike Baldur's Gate, Icewind Dale doesn't feature NPC companions, but instead the player build their own party from scratch. Other than that there are only very minor differences in gameplay, such as spells and the likes. It was released in June 2000 and also got an Enhanced Edition by Beamdog Inc. which was released on October 30 2014.

Icewind Dale II was released on August 27 2002. Unlike all other games in the family, it doesn't use Advanced Dungeons & Dragons 2nd Edition rules but instead Dungeons & Dragons 3rd Edition. There has been no word so far on wether or not there will be an Icewind Dale II: Enhanced Edition at any point.

Over all there exist two main games in the series and two expansion packs for the first entry:
 * Icewind Dale
 * Icewind Dale: Heart of Winter
 * Icewind Dale: Trials of the Luremaster
 * Icewind Dale II
 * Icewind Dale: Enhanced Edition

Setting
Like Baldur's Gate, Icewind Dale takes place in the Forgotten Realms and centers around the eponymous Icewind Dale region, including Kuldahar, Easthaven, Dorn's Deep and more, which lie at the very northern end of the Sword Coast.

Cross-references between Games
In addition to general references regarding the shared setting, the games also share a number of game specific references between each other:
 * In the first Icewind Dale Erevain Blacksheaf's journal, which can be found with his corpse in the Dragon's Eye in the first, reveals that Erevain is Xan's cousin.
 * Baldur's Gate: Enhanced Edition, Baldur's Gate II: Enhanced Edition and especially Baldur's Gate: Siege of Dragonspear re-use a lot of assets from IWD.
 * Belhifet is both the final boss in IWD and SoD.
 * Hephernaan has the same character model as Jerrod.
 * Icewind Dale: Enhanced Edition is a port of the original IWD into a modified version of the BG2:EE engine.
 * The collector's edition of Baldur's Gate II and BG2:EE feature a bonus merchant named Joluv, who sells IWD themed weapons and gear.
 * A series of scrolls by Alveus Malcanter, who is featured in a series of humorous promotional videos for IWD:EE, can be found throughout SoD.
 * Edwin also mentions him in SoD: "As Alveus Malcanter said, 'The wise general does not lead from the front of the army.' Think on it."
 * In a promotional livestream by Beamdog Inc. for SoD in early 2016, Mark Meer played the game in his role as Alveus Malcanter.
