Here's the bottom line. Not every game is going to blow everyone's skirt up. In the case of this admittedly peculiar game about an admittedly peculiar niche of warfare, either you understand and we don't need to explain or you don't and we CAN'T explain.
There is no alternative but to explain that we love the game for what it is and don't care about what it isn't. The game fit US, not we fit the game.
For many, the game won't fit them. And that is not a bad reflection reflection on the people who just don't understand why Silent Hunter is great. It is strictly a neutral and true observation. If you choose to take offense to it, that isn't my problem. The truth is sometimes unwelcome.
Welcome to Subsim. I encourage you to try it for awhile to confirm or refute your first impressions. You might want to try my Slightly Subnuclear weapons: torpedoes and gun ammunition. You might try Neon Deon's Balao Cruiser with four 5" gun turrets, which using my Slightly Subnuclear Deck Gun ammunition holds the record, sinking well over 100,000 tons in 8 minutes and change. Sorry, I don't do god mode mods. My submarines are just as vulnerable as the real ones, they just have "enhanced" weaponry.
But personally my first love is a realistic cruise with Trigger Maru, where a 30,000 ton cruise is cause for celebration and enemy escorts have sharp teeth and like to bite hard. Where airplanes can see you at periscope depth and end your miserable life without you even knowing they were there.
And yes, I love the setup, taking an hour or so of real unaccelerated time to establish enemy course and speed, select the best attack method for the situation, determine TDC settings, position my boat and then if all goes according to plan....fire one!
Sorry you're disappointed at this. Sometimes communication is not possible for someone who comes into an established forum and insists that all ideas conform to their own. Discovering other ways of viewing the world is fun.
