DW is hard for most casual players and the graphics are not appealing at all. This deter most gamers from trying out.
Add to the fact that modern naval engagement involves top secret data and information very much the kind of information that world governments want to conceal or purposely misguide the public.
DW fell prey to this too with no exception.
For example submarine countermeasures which in Sub Command didn't detonate spoofed torpedo now do though then Sonalysts release a patch to make this optional through a probability number.
Other thing such as the towed decoy not able to detonate incoming torpedoes. But the community soon found out the truth through simple logic that if sub countermeasures did detonate spoofed torpedoes why would navy warship still tow a decoy?!
. That leads to the answer that sub countermeasures don't detonate torpedoes and as last resort navy warship tow torpedo decoy to detonate them.
Things like this made me believe that most government don't want to see a society well informed and knowledgeable about military aspect of the state. It's understandable though since they regard much of this as a war winning information hence the confidentiality. Public could very well also consist of members of the enemy.
I'm saying that modern military games involve and will always involve substantial dumbing down and purposeful misguided, inaccurate implementation of the real thing be it ground, sea or air warfare.
