First, you create your entire party of six, rather than finding and adding NPCs to it. IWD and its freshly hatched sibling differ from the other IE-based games in several respects. For those of you who didn't catch the original IWD, it's a Black Isle Studios' fantasy-based CRPG (computerized roleplaying game) that uses the 2D Infinity Engine, like the extremely popular Baldur's Gate series and Planescape: Torment.
