What older game deserves a graphical update?

It doesn't happen often, but when classic MMOs are treated to a graphical overhaul, it feels like a cause for celebration. A couple of weeks ago we heard that Anarchy Online's long-in-development new graphics engine had started beta testing, and not so long ago RuneScape jazzed up its looks with a new iteration. It remains to be seen whether a spiffy visual overhaul will extend the life of the game and/or draw more players into the game, but it's exciting no matter what.

Fans of older MMOs always seem to be clamoring for improved graphics, so let's make that the topic for today's discussion. What older game deserves a graphical update? Would you go back and play it if it got one?
