try starting the game using a different shortcut.

right-click on the game in your Library list and choose Create Desktop shortcut and use that to try to start Naval War.

click on the Steam icon in your taskbar and then on Naval War: Arctic Circle to see if it will start that way.

I am used to play Dangerous Water with the LwAmi mod, so I am somehow surprised then disapointed with the quality, accuracy of NW:AC, especially with the communication work done before launching the game.

It is a nice game as an introductory point to the genre as much as Global Conflict Blue which is free, yet GCB is more accurate.

Too superficial for my taste.
