For the record, I'm pretty sure I understand the general point that you're trying to make Flying Arrow, that games that simply try to emulate the ability of a real actor to convey emotion through their performance in a realistic way are on a fools errand, and though I'm not sure I agree entirely, I do see where you're coming from. But I do have to disagree with the idea that blocky sprites didn't emote. It's outright not true. They may not have conveyed emotion through realistic facial expressions or body movement, but there have been plenty of examples of sprites which conveyed emotion through their animation. FFVI perhaps being one of the better examples of fairly simple sprites which convey a lot of emotion considering their low level of detail.
I won't try to argue that it approaches the level of a real actor, but it didn't have to to get the point of a scene across in its own charming way.
