Re: Malta - I like to hit Malta with the Italians because it negates the British NO for virtually the rest of the game. It’s also so central in the Med that it’s too easy for England to snipe in, hit something and land there - something I might generally over look.
Re: Germany in Egypt - If I can use an Italian transport to shuck 1 Inf, 1 Arm into Egpyt with Germany, as just extra defense I will. Takes longer, but saves building a transport and having to defend it. Unless you are going HEAVY anti-England (i.e. thinking of Sea Lion and or waiting on Russia until the last second while focusing on removing England’s teeth and keeping them removed.) In which case, I am going to want a German fleet in the Med so that the Italian fleet can move along the Middle East Coast and/or Eastern Africa coast for money grabs. This is more in an effort of Japan winning in the Pacific instead of Europe winning, which, IMNSHO isn’t a decision you wanna make Round 1 anyway (I like to see where the dice fall on Round 1 before picking a campaign strategy. Let’s me know what I have for Round 2 on the board and you can usually pick up what the Allies plan to attack first by where they move and build.)
Keep in mind, just because the allies do something, or your dice tell you something, does not mean you have to be locked into your campaign options! Never let a good disaster for your enemy go to waste!
