But polygons aren't everything. Sometimes there are visual treats, little flairs of animation, just the right amount of detail and lighting. Sometimes a game that you weren't expecting to impress you with graphics manages to do so -- even if you're generally not someone who focuses on graphics. Whether you're running around in Age of Conan or Final Fantasy XI, there are vistas and pictures that impress above and beyond technological constraints.
So, when have graphics struck you and made you take notice of something? Was it a game that looked astonishingly well-rendered for its time, or one that was fairly basic even when it got released? Were they stylized in a way you found appealing or just surprisingly realistic?
