I don't know how popular it is today but I'm quite sure people are still playing it somewhere. I still have mine for my commodore 64 and almost wore out the disk flipping it over endlessly to "engage the enemy"

The manual that came with it was supurb and taught me things that were very useful in later games. Maybe someone should reproduce it, making S/C and D/W more understandable to most folks.... BTW, what ever happened to the sea lance asw missles and the swimout torpedoes??
