There's always the possibility of a more modern sub sim, possibly set in the Cold War, like Microprose's old Red Storm Rising (based on the Tom Clancy novel of the same name). But such a sim has to have an immersive environment similar to SH3, or it will go nowhere.

Also, it has to be realistic. What do I mean by that?

I worked with some people of very low IQ in a sheltered workshop. Among the many things there to stimulate them were computers.

One of the things I noticed was a young man whose IQ was 68, who was going quite far into the campaign of Red Storm Rising. I thought that was marvelous. Then, one day, I decided to watch him play.

He would bring his sub to the surface. Yes, he surfaced the boat! Then, he ran it up to flank speed, turned on all of the sensors, and started launching missiles and torpedoes. When the inevitable counterattack came, he launched countermeasures and maneuvered wildly.

I watched him destroy a complete Soviet surface task force, with six ships, in this manner. Needless to say, it wasn't particularly realistic!

Much more is needed than eye-popping graphics to make a subsim realistic ...
