And if "BG3" hadn't been announced and you showed it to someone who'd played DOS2, they'd immediately think it's DOS2.
Um... show representative screenshots of D:OS 2 and BG3 to any of your non-gaming friends, and see if they fail to identify the differences in graphics and dialogue system.
One would have to be blind to not see them as being very much the same, other than being a little more "imporved" like one would expect going from D:OS2 to a D:OS3.
