I've almost finished creating my world map, here.

Next I want to get working on mapping each region of the globe in some detail. I've tried this before and found that any overlap between such maps is extremely difficult. Is there a good projection to use for this purpose? Almost every projection type distorts the geology as far as I can tell, making it very difficult to overlap maps. I'd love to know if there's an answer to this.

Or am I doomed to painstakingly redrawing all of the cities and roads of my maps?
