Just a thought for players with higher-end setups: an option (that can be turned off for low-end systems) to use HDR lighting effects. Even with the concessions HTC needs to make to graphics to have the game playable on as many different systems with the inherent speed issues of the online format, I'm continuously amazed at how much difference HDR can make in the atmosphere of even relatively low-detailed graphics. This would especially be noticeable in how sun effects are displayed, especially if the sun in the game is set up to actually function as a light source.
