[Captain Vlad]

I think to keep most people's interest you'd almost have to have a hypothetical war situation.

It might, however, be possible to have several hypothetical war scenarios to involve yourself in, from a limited war around some Soviet or US client state to full-blown WWIII. I might also be possible to have the option to start a career during peacetime, and war starting at some random point during...you might get in a patrol or two doing peacetime stuff before the balloon goes up.

If anyone remembers F-19 Stealth Fighter, it had options for 'Cold War' scenarios, which were the same, objective wise, as most of the open war assignements, but were scored differently. You no longer recieved points for destroying oppurtunity targets, you recieved them for remaining undetected by the enemy. Peacetime missions for a Cold War SH V could use similar logic, with higher renown rewards for doing whatever it is you're doing and no one spotting you.

The possibilities for historical scenarios are great. Trips under the North Pole and such.

I do hope that if Ubi-Soft decided to do such a thing, they put the era in the '50's and early '60's. GUPPY conversions, early nuke boats, and new-build diesel submarines of the era are far more interesting to me than more current stuff, which has had it's time in simulation sun many times anyway.
