Considering the "sterling" success of Silent Hunter 5, this would seem like an incredibly stupid question. However, that game deals with Uboats, which is an entirely different scene altogether.
The only reason i think this is even a plausible question in the Pacific theater is because the iconic Fleet Submarine is 6 bow tubes, 4 stern tubes, propeller guard, and look outs in the periscope sheers. Any submarine that doesn't have that, (at least in my opinion) is simply an earlier design evolution, because all boats, ultimately serve the same purpose. That of the Fleet submarine. Originally envisioned as a scout for the fleet, but later used as a long range attack submarine in the largest ocean in the world. ( As opposed to Uboats that had submarines built for different purposes)
Anyway, i'm curious to see how the community feels about the concept of "One boat done really well". As opposed to "many boats done fairly well." as applied to fleet submarines.
( Sometimes i think i get a good idea, but really i might as well be smoking crack. That's what i'm trying to find out here.

The obvious third choice of "Max detail and max choices" intentionally omitted because I cannot deliver that. The second choice has already been delivered, its the first choice thats the hairbrained idea.
