The pc RTS Empire Earth has a German campaign. Half of it is WWI and the other half is WWII. It's really great. Starting in 1939 you need to conquer Poland, Norway & Denmark, Benelux & France before the end of 1940. Another battle is the Battle for Britain I think. And a third one is Operation Sea Lion which was never executed because Germany lost the Battle of Britain, but you get to invade Britain from Northern France and need to destroy Buckingham Palace. I can recommend this game to everyone. The Russian campaign is epic too.
