Arguably, for cRPGs, the graphics are actually a lot. It is a rare for one to get this much attention to visuals. Same with animations, even games like ME and DA, which are praised for their cinematic stories, are super super stiff in conversation animations with characters typically doing like 1 of 2 arm and head movements. By comparison, Astarion emotes more than any NPC in those games outside of like preset one off cutscenes, and even then Astarion emotes a lot. For a dialogue heavy game, this is very very good, and allows them to do things like give characters tells for lying without having to always spell it out in the writing.
