Interesting - will be keeping an eye on this. Ground seems a bit bumpy at mo - unnaturally rough to my mind but will see how it goes and comment later on.
I think it's not the roughness, but the uniform roughness. You should have some larger features like ridges and mountain ranges. The base layer of hills shouldn't be flat, if you know what i mean.
A matter that I am fully aware of. It is still in the rough stages at this time and hopefully (assuming I have time today) I will be tweaking both the elevation model and the surface maps to reflect erosion and cultivation in some areas. I am also planning on laying out the major roads and rivers, but again, it might be later this evening before I have a chance to work on things because the #$%^ idiots I work with have, as is often the case, screwed things up again and guess who they call to fix them . . . .
