Aside of this, nobody had stand a chance against the Home Fleet and hence the Mediterranean theatre isn't good for PBEM.
You've mixed the Home Fleet with the Mediterranean so not sure if I fully understand what you mean. But if its the Mediterranean war you are talking about then your coment is not right IMO.
The Mediterranean battles are some of the most fascinating of World War II. Maybe not as impressive in scale as the large carrier based actions of the Pacific, but no less interesting for that. There were a variety of actions ranging from Human torpedoes at Alexandria, set piece destroyer battles, carrier launched air strikes and Fleet actions like Calabria.
With the French Fleet out of the picture in June 1940, the British need to look after both the Eastern and the Western Med, and the decision to keep Malta in the war, meant that the RN were stretched to breaking point. The Regia Marina had a number of opportunities to inflict great damage on the Royal Navy - but rarely capitalised on them for a number of reasons.
The new Italian battleships of the Littorio-class outclassed anything the British could offer and their superior speed gave the Italians the important advantage of being able to dictate battles.
The Italians boasted far more heavy cruisers than the British and of course (in theory) they had a giant, permanent aircraft carrier jutting out and dominating the central Mediterranean.
Almost all battles stemmed from either or both the British and the Italians need to get convoys to North Africa/Albania and Malta/Greece. This made many of the engagements real cat and mouse affairs. Do I protect my convoy or attack the enemy's?
With such a fine balance of forces, such a game would be better matched than say WITP. Add in options like the Germans seizing the French Fleet, and the British would have an even bigger struggle on their hands.
