Both Campaigns are Cool ! each for different reasons and in different
ways. The Battle of the Atlantic you can study your whole life and
never finish though. The american campaign in the pacific is also very
cool to learn about and has many great moments with many Intruiging
aspects of the strategic war.

They are different studies though as they are different campaigns.

The German attempt to strategically strangle an Island nation didnt
work for many various reasons

the American campaign to strategically strangle an Island nation did work
In spades. and with quite a few less boats than the germans.

the asw study and length and wholesale volume of the "trench warfare
at sea" in the atlantic gives that battle an appeal in the sense of the
shear mass of the study.

when comparing the two campaigns you have to remember the differences
between those campaigns.
by the same token the only valid comparison of sh3 and sh4 should be based not on comparing with GWX 1.03 (or 4) but with comparing vanilla
versions of both.

how many ran into non rendered shorelines in the beginning with sh3.
it had many problems. in a vanilla comparison they arent as far apart.

I love both games and I Love the whole subject not just these two
campaigns.
