Well, it's up to the predictions - is it going to be a sure "blockbuster" in submarine warfare closer to Silent Hunter... or aimed to fistful sub/crew management fanatics...
I bet that my generation of Grey wolfs veterans will not have a patience to feed, entertain, train, heal,...the crew >or to check out engine room - valve by valve...
The smartest approach would be to offer simplified, medium and realistic options - with a customize each detail option.
This way you would grab 99% of sub-simulation fans market.
People who work or learn, care about real kids and elderly parents > certainly will not have inspiration to care about "crew members".
