I always thought Zychion would look good in the rain:

Had to vote yes, since a day/night cycle would add an interesting addition to the game. As would weather for that matter, giving a different feel to certain areas of the map. Lighting in games often helps set the mood, and to be honest I'd find it much more exciting going to hunt somewhere where its dark - perhaps even with a storm if MindArk ever create weather. It'd give the game a more 'realistic' feel, rather than having just static lighting and skys.
Since you can't please everyone, perhaps open up an underground section - like a huge mass of caverns and tunnels. This way people who wouldn't want to hunt in the dark could stay above ground, whilst others can explore in the darker areas. I wouldn't say its a perfect solution, but at least offers a new place to explore, somewhere different to hunt/mine and its in the dark.
