Notes:

*1* Rename desert and change graphics. not much of a difference.
*2* I think that these small defence bonuses are in for balance of defence - offence, would leave.
*3* Increased base of mountains to make them equal to hills. imho mountains should be better then hills.
*4* Early ships ignore coast move cost, later ships sea, the latest ship ocean costs.  keeps early ships to coast.
*1* is only terrain to posses disease, with text changed to attacks of evil trees, very dense tree graphics.
