Sub-Map functionality can open a huge range of options for modding CivIV. Some options come to mind: Tactical Combat can make or break a strategic decision in reality. Building placement can greatly affect the efficiency of a building. RPG can add insider elements to turn the tide of strategy. Of course the options dont end there. Game play modifications that are enabled by Sub-Map functionality are only limited by the imagination! Please comment on your ideas for the use of this mod and what sort of functionality it should have. This is an SDK project. Please bring to the table ideas of the best, safest, and most useful ways to implement this code. ANY IDEA IS A GOOD START Dont be ashamed of what a flaming wolf might say.
