I've already said that the game lacks emotional intelligence.
You can kick ascended Astarion in the balls in a romance scene, but can't hug him if he chooses not to ascend (a good place for that hug would be when he says he wants to feel alive again before leaving Cazador's mansion). Can't hug Shadowheart in a moment where any at least somewhat emotionally literate person would consider offering comfort. But hey at least you also don't get an opportunity to slap her for anything.
