Any differences between how the three eras are represented?
Chapter I of the rules give the standard instructions (and optional rules) common to all three eras. Subsequent chapters (II, III, and IV) give era specific options and Game Tables and scenarios. There is a chapter devoted to “streamlined rules” for beginners, and Designer’s Notes, and, finally, a chapter listing, in tabular form, all the ship ratings (by nation and class and era) used in the game. To give some simple examples, fire ranges differ according to era, plunging fire is applicable only in dreadnought and World War II scenarios, ramming and striking only in pre-dreadnought scenarios. and so on. The idea is, when you are replaying, say, Tsushima, you should approach it as Tsushima, not as Jutland “a decade early” (and visa versa!).
