The "rapid release" of submarine sim's, is basically, us.... living in a bubble, or so is my thought.
The name of the series, is no accident. The "Silent Hunter" name goes back to
Strategic Simulations, Inc. who published the
first of the series.
Silent Hunter was an SSI title, and SSI was acquired by ubisoft. My guess is Ubisoft Romania as we know it, was sort of a legacy remnant of that era, only with newer employee's as im sure the original developers moved on some time ago.
