Changing the movements points allowed for certain terrain

[orclover5]

Is there a submod available that changes the movements points allowed for terrain like swamps, hills, forests and such, or can someone direct me to where I can manipulate the movement points assigned to roads. I think it would be great if there was a major disadvantage to trying to cross a swamp or hilly region which will make dominating roads that much more important.

You could just mod it in your self

Takizama, can you tell me how to mod it myself... I can't seem to find any documentation or the right file to change the terrain movement points.
