personally, i believe that if the writing is sufficient, there shouldn't be a need to use complex graphic hocus pocus to elicit an emotional response from the player of da:i. even then, clever direction can overcome graphical limitations. if you really want to "show" somebody weep, put the camera angle behind the weeper, and have them drop their head into their hands or (eye-roll) fall to their knees while adding the appropriate sound-effects. i would rather have bioware use their limited art resources for things other than making a love-interest in the game visibly blush... things such as, well, anything else.
and i am glad to hear that you do not have some peculiar fascination with working liver cancer patients or individuals with advanced scurvy into the game.
