At the moment there is only the surface topography with its different textures and trees that form the landscape and its natural barriers. This seems a little bit plain. As an example, it is way too easy to move in a forest, it should even be difficult to enter a forest, because there is normaly a hedge of bushes and smaller plants around forests, which is not easy to pass. And within a forest there should be big boulders, fallen trees, Fern and stuff like that. Same goes for fields, there should be boulders, rocks and such.There are to be different rockformations, like cliffs, canyons and natural caves. This would improve the gaming expierience a lot, i think.
