I had a similar development in my last match. Germany built Carrier and Transport in the Mediterranean on G1 and was lucky with his attack on AES (3 troops standing) and in the counter on UK1 (cleared AES but couldn’t lost all groundtrops. had to land Bomber and Fighter next to it, so the fighters from the carrier could take me out and land on AES). The result was a complete Africa for Germany, a quite unusual occurance.
The match went to the Allies, nevertheless. Germany overcommited to Africa (having 35 IPC of troops there, plus AC and additional transport) and played some horrible mistakes in the endgame, not fortifying Germany enough when it was threatened by UK/US + Russian troops from East Germany.
Allies ignored Africa completely, except for turn 2 when it was used as a distraction for the impending invasion on Norway and for a combined allied fleet.
After having played 10-15 matches lately, I tend more and more towards limiting African investment. Like Hobbes said in another thread, if the Allies want Africa, they will take it. And strengthening Africa with its 1 and 2 IPC countries (11 total) considerably weakens the eastern front, where there are so much more interesting targets.
Currently, I’d take 5 INF 1 tank over the Battleship anytime. Or Bomber, INF, tank.
Africa has no victory point, no strategic advantage except for lowering UK income / vs. lowering Russian income. But then, it’s Russia who you have to beat if you want to win.
So if anything, I’d go for an AC + tran for the Med. It has basically the same effect, but adds another route to Caucasus. On the other hand, neither a Carrier nor a Battleship will ever defend either Germany or your panzers on their way to Moscow. So… nah…
