[Purulent Carcass]

It looks very much like Baldur's Gate. I am willing to place bets that NwN has this beat in every category since it appears that you can do every single thing in NwN that you can do in this. So far, NwN is the closest thing I have found to simulate actual D&D. With the 14+ years of content added to NwN, its hard to compete with it. Let's not forget after a roughly $20 purchase, NwN is utterly free to play.
