Unfortunately, the full version has almost only disappointments. At least once it comes to war.
Peace phase:
The micromanagement is to master well after some back-and-forth tinkering. The automatic deportation of personnel and goods can not be trusted, unfortunately. Programming is so bad that you wasted ship space and time unnecessarily. Overall, the game is quite a time investment before the war. Unfortunately, the manual will help not continue in many detailed questions.
War phase:
Even on the "hard" difficulty level of the opponents is going raggedly. Unprotected enemy convoys are hardly ever attacked, but only the bases. In selecting the targets the computer does not pursue higher strategy.
The real drama begins, however, in Tactics mode. The opposing fleets are placed so close together that even the destroyers are now in firing range. One consequence is that carriers are always sunk and so its "historic role" does not do justice. For larger meetings they still fall with full hangar, because the game only allows a limited number of active aircraft.
In addition a large number of errors and inexplicable system crashes.
The overall conclusion: A nice idea that has gone totally immature and full of bugs in the sale. For me it is now up to a few neat patches in the corner!
