I don't get it Wave Skipper, if the game doesn't model torpedo failure or "the lousy command system" the game isn't realistic enough for you, but if the game is what you call "realistic" then it's too boring?

You want to play a Japanese commander with subs that only went down to 30 meters like RO-class subs? With a doctrine that does not allow you to sink merchants and therefore waiting for a warship to cross your path? That's what I would call a dull game.
