dUMBELL, I fully realize that this isn't finished. If you understood the points I made in my previous post, you could conclude that if something such as varied geography were to be added to this. It wouldn't be plausible to do with what is already there. The hills look the same, modifying them to look different would not only be strenuous but also unsuccessful. And the path, thats flat too, you'd have to destroy it all. I guess really what I'm saying is that maybe there needs to be another restart. But if you disagree with my points feel free to argue against them. Just don't make a statement without any backing to it.
Just saw Jervan's post, as of now my point stands, but it could get better.
