IMHO, to use the name "Silent Hunter" for a early cold war era, or nuke subsim will be an error.
Silent Hunter saga is a WW2 subsim saga.
For a nuke subsim we have Dangerous Waters wich is so good enough.
For an early times of cold war, with no nukes, i think so there is not too much action... will be too boredom.
At first SH III and SH IV are so far to be perfect.
We have not thermal layers modelated on SH III... we have not the water trap to pick up external water and found the thermal layer neither ... why ? because there is not thermal layer modelated.
We have not batythemograph modelated on SH IV.... it was on SH I... 12 years ago... into a DOS subsim.
We can have all the sub interior modellated... with cinematic scenes... torpedo load up, repair actions, flooding.... if i dont remember bad, it was into Fast Attack many years ago... it was a DOS subsim, i have it here in my desk. You was able to see scenes of the crew loading torps and more during in game.
We have not an "ingame whiz wheel", it can be done, i made it for SH II.
We have not a "launch debris" function on SH IV like was in SH I.
SH V at first must to be a perfection of SH III and IV, may be aboth in one, German and USA subsim, may be with the add of Japanesse and British playables subs too.
Plus...
We have a lack of two things in the world of simulation...
1]
A good, WW 1 flight sim... some thing like Red Baron 3D, wich was an too advanced flight sim for his age... may bebetter than many actual... its damage model and its editable flight model was amazing. Its campaign was amazing with cinematic effects and real age news.
2]
A good WW 1 Subsim... where the deck gun was the main gun... with the abordaje simulation.
I think so, the improvement of SH III and IV is at first, and a good WW 1 subsim is at second...
