Another point here, People tend to play what they understand. Allot is said about the u-boat war but few things about the Pacific submarine war. I myself had the mentality of Pacific=boring. But once I researched and understood the fleet boats war better, the tactics and reasons I became more fascinated and began to sim it more.
Its truly an exciting thing to study. U-boats get the glory but failed, Fleetboats get the cold shoulder but exceeded better than even I could comprehend.
My advice is study the history and the sim will come alive.
