yeah it's hard but it's also a brilliant gaming experience
my most fun career ever saw me through the second half of 1942 and alsmost all of 1943, surviving some thrilling encounters. Eventually I died just before newyear 1944, from stupidity, when i attacked a convoy in the Med without having noticed that there was only 150 meters under the keel
hitting a few ships from a convoy and then playing hours and hours of cat and mouse with the escorts, in real time, is just the most exciting way to spend an evening, short of fornication
