Now it's in the news:

I have had my eye on this game but did not realize that a Canadian frigate was part of the NATO fleet. Capable as HMCS Halifax may be in 2012, I can't imagine that she will do so well in a 2030 conflict!
The devs are taking a few liberties and "best guesses" with regard to capabilities. I think you may be surprised.
I'm watching this but I don't think it will as realistic as Harpoon or Command. The previous videos look pretty much like Janes Fleet Command. Only subtle improvements in graphics.
