I prefer Spring 1942 to both Global and Anniversary edition.
Global takes a long time, has a lot of special rules - but has no fog of war. In my opinion, if you're going to try to make a serious detailed war game with political rules &c &c &c, you need fog of war. Larry Harris you have failed me.
Anniversary edition has some interesting options with national objectives and technology. But the increase of size of the map means gameplay boils down to very much fixed lines of play once the opening moves are done. In Spring 1942, the smaller map allows quicker changes in position, so is a more dynamic game. Which certainly isn't to say that Anniversary edition doesn't have some appeal to it.
Classic, Revised, and Spring 1942 have different maps. When compared to Spring 1942, Classic is very much different, and boils down to a fight over Karelia. Revised gives Japan more interesting options as transports can hit Western Canada from Japan in a single turn. But it's best not to mix maps and rules; mixing them up will mess with your head.
As far as printing an Anniversary edition map and rules, I don't know that anyone would openly condone that as it may not be legal under copyright laws. But since Anniversary edition is out of print, well, that's interesting. Really, what can one do? Anyways, no comment.
Anniversary edition has Italy and China as powers. Maybe you could whip out a can of spray paint or something.
