Welcome to the most infamous and corrupt city in the Forgotten Realms, the port metropolis of Westgate! Explore the secrets of this cutthroat capital of the Dragon Coast, where anything goes and everything has a price, and attempt to unveil its darkest mysteries before they consume you. Choose your allies wisely in this city of treachery, as you seek to encounter the rulers of Westgate's underworld, the deadly Night Masks.
Actually, this is done by an independent developer (Ossian Studios), and it's generally well designed. It seems the only flaw is that it reveals storyline secrets too fast, IMHO.
