I'd buy it!
From the few posts I've seen describing cold war era sub sims as a "snooze fest"...
I would say first, go read Blind Mans Bluff. And secondly you're missing the point, it would obviously be a simulation of a war event in the cold war era, similar to Red Storm Rising.
Who says you have to immitate history? Would be cool though if I could create a special ops sub to search the bottom with a tethered submersible for communication lines and them send my dive team in to tap the line and gain an advantage against my adversary.
