I would add the atmosphere, but I need to code Framewerk in C#, which is not an easy task.
I would also add some ground cover as you suggested, but I have found the ground cover provided in your (wonderful) pack not quite fit for MMORPG-style bushes and such. Too subtle, probably more useful for FPS, which is what you design for.
The model will not even be used in the final game, but only for testing, so I could care less. But thanks for the comments
[by the way: If ever you feel like making some MMO ground cover / old (fable-style) fence models, make us know I'd be glad too buy them]
@Josh: I know there is an improvement between 9600 and 9800. I'm just wondering how big it is.
