Hi, im a new member of twcenter and also a beginner to modding and therefore seeking help from the advanced modders.

I have played Rome Total War a lot and enjoy it but want to make my own mod by changing things to my liking i want to change the campaign map and enlarge it so that it includes Scotland, Scandinavia, Iran, Pakistan and the west-northern point of India but what tools do i need and how to begin.

thanks in advance for the help.
