Showed the game (I have Limited Edition) to a friend of mine who is so impressed, especially witgh the designer, that he intends to get his own copy.
That said, he pointed out a flaw in the list of components for the 1890s designs in tower/mast structures. He commented that, while many warships used the Type 1 Forward Tower Structure, in the 1890s the overwhelming majority of warships, especially capital units, tended to have a fairly simple pole rig structure at the rear of the ship, with a fairly simple spotting top mostly for plotting shot. He sugests amending the designer so that pole masts are a viable option.
