Cohaagen I have to agree. Last year I suggested that it would have made more sense making SH4 about the Japanese subs. They certainly had a lot to face. But the Pacific was mainly about big fleets and huge naval battles. Then there was the fact that American subs had major torpedo problems for the first year - larger than Germany did. So real American tonage sunk during that early period was pathetic. However I will likely finally buy SH4 and play it - when I get around to it.
