I love military history in general so I'm always intrigued by new things that I haven't yet explored. My sub origin is much more mundane than most.
I was readingthrough my latest copy of PC Gamer and came accross a preview of a very interesting new subsim. It was called SH3 and I was intrigued to begin with.

Then a month or two later there was the full on review and I imediately searched out the closest copy. I tend to trust PC gamer reviews and they gave SH3 a very very good review. So before I could scrape together the necessary funds to purchase the game ($70!!!) I went to the library and got every sub book I could find and just started reading. It just got out of hand from there.
