My grand father served aboard a corvette (the name escapes me at the moment), so my father always had a great deal of interest in convoys, as well as the Battle of the Atlantic.
So, he bought SH2 one day. Couldn't figure out how to turn the sub and gave up on it
. Me being the child who plays with everything, soon picked it up, and at 10 years old was hunting convoys round the Atlantic.
Once we renovated our computer room and disk got lost so I was out of a subsim for a while. It was only after I happened upon Sh4 and then 5 that I really got back into subsimming.
