Looks great to me so far.
But what is this about 1945? Has the entire year been omitted from the campaign, or is just not possible to start a career in 1945? In SHIII, you can't start a career after 1943, but you can still play until the end of the war - is the situation in SHIV something similar or a complete cut off? I hope not, as playing in 1945 would actually add another challenge to the game - trying to find enough shipping to sink.
