I really like all the "story" maps that have the paths and events marked on the Atlas maps.
Unfortunately, I find the "Biblical World" maps to be less useful. I think the next major step would be to illustrate the extent of the various nations/empires in the different periods of history, like so many of the "back of the Bible" maps typically do.
For example, Biblical World - United Kingdom should show us the extent of Israel's territory under David and under Solomon. Also, how about the territories of the surrounding nations (Moab, Edom, etc)?
Biblical World - Divided Kingdom should show the extent of the Northern and Southern kingdoms.
How about a Biblical World - Tribal Allotments for the land allotted to each of the 12 Tribes?
Biblical World - Babylonian Empire? Biblical World - Persian Empire? Biblical World - Greek Empire (both united and divided)? etc
