I remember I was about 8 or so (I'm 31 now) and a friend had this game....well I played the heck out of it. I'd spend hours and hours just patrolling on the map. That was my first subsim experience. And looking back, it wasn't a real big deal then, but now it's a huge deal especially with these new subsims. It was a very innovative, well thought out game. In fact, I still have it.
Nothing like tearing apart Kaibokans and destroyers that are coming straight at you. :
