How can it not be close to BG when it's based on Dungeons and Dragons
Back in the day there were multiple DnD based series, most of them in Infinity Engine: Icewind Dale, Baldur's Gate, Planescape: Torment, Neverwinter Night. All of them were quite distinct, not only in terms of atmosphere, location and story, but purpose, focus, appeal, structure, design. Using DnD setting and systems is just ingredient - how one uses it, and for what purpose is another story.
