I'd like to talk for a second about extreme long-distance connections, and the general advisability, or lack thereof, of, um, thereof.
I've been looking at the cheat sheet, and some of the following connections set off a couple of alarm bells:
British
Ajax-Achille and Leviathan-Achille
Bellerophon-Tonnant (this one looks like it goes through a couple of bowsprits anyway, and fyi, Beller
ophon is still misspelled)
Bellerophon-Thunderer
Victory-Swiftsure (this one I'm a bit on the fence about)
Neptune-Royal Sovereign
French
Pluton-Neptune
Scipion-Neptune
Pluton-Themis
Spanish
San Juan de Nepocemo-Argonauta (this one I'm also on the fence about, but maybe my eyes are playing tricks on me but they only just barely connect, about which more below)
Part of my argument is for legibility, for a few of these one could make a legitimate argument that they don't appear to connect, but my broader issue (warning: history weenie approaching) is that it doesn't seem to make sense in the context of the battle. There's only a certain amount of sea over which a ship of the era could project its power, and some of these connections are practically warps to the other side of the map. I'm all for connectivity, but connections like Ajax and Leviathan to Achille are basically warping across two thirds of the map. In keeping with the theme, it should take some, well, sailing to get from one area of the map to another.
I'd be particularly inclined against long-range British connectivity, since it's already easier to move around the map via British ships than it is Spanish or French.
Any of these connections that end up in the final map, you might want to think about subtly clarifying that they are, indeed, attack routes. Moving some ships around, even a few pixels in some cases, would work wonders. The upshot is that connections that are more than a few boatlengths should be made as obvious as possible, there should be no need to break out a ruler (or refer to the cheatsheet) to know that a given two ships are connected.
On an unrelated note, perhaps the flagship bonus could be "+1 to any bonus of the same nation". Actually, let's get back to that one when we get around to discussing bonuses.
