why we have Malta but not Crete?
Crete was invaded before spring of 1942 and it posed no problems after occupation. germany controlled it till the end of the war
Malta was a thorn in Italys side. Its air base was used to sink Italian transports and harass shipping and provided coverage to british convoys traveling to suez canal. It was also a fortress that was considered very difficult if not impossible to crack. Its a much greater strategic point for UK and against the italians.
other than that it woul clutter the map with too many medd islands
