I think you are misunderstanding. It isn't that they didn't make a game YOU want (realistic sub sim), its just that the game is completely unfinished and riddled with some unplayable bugs. And saddled with a ridiculous DRM system that we have to read about every other day "Ubi servers down again". The bugs and DRM are the problem, not the lack of realism. Read the reviews.
It isn't like this game was released, highly polished with minimal problems but was just "too unrealistic" for some.
The game, in its released state, was and is garbage.
Come on, destroyer groups that maintain course with you and just plow into islands? (that plus the game killing morale bug, UI issues, ships that are in midair and unhittable, etc. etc.)
