Fair enough. That's you and that's some others. That's not me and it's not some others. D&D is at the heart of all RPGs. While there are likely some developers who did not want their video game to be a faithful version of the table top experience, Larian does not seem to be one of them. And I would expect WotC isn't either. Were the creators of the original BG trying to get away from the table top experience? I highly doubt it. They just did the best rendition of it to date that they could.
and BG is at the heart of all computer RPGs.
Oh how mistaken you are. RPG video games didn't start 1998 you know? Nor did it reach a climax then either.
