This game really deserves a 5 but lack of documentation and some clunky user interfaces makes it fall short. The gameplay and graphics are quite well done and make this a great addition to any naval gamers collection. You will be left having to figure some things out for yourself as the documentation merely hints at some fo the features in the game but after a little bit of playing around you will discover these. Most are in the "on base" portion of the game and therefore don't distract from the actual gameplay itself.I wish I would have purchased this sooner - it's a lot of fun to play.
