Hi,
OK well the first thing I should point out is that I haven't played the game outside of that first demo game...
There are counters for torpedoes. When you fire them you place them against the target ship in the attack phase but you don't actually resolve the attack. In the end phase you roll the attack dice and actually carry out the attack.
I guess it could get complicated if there are many ships or submarines firing them off.
In the demo game the guy running it handled them in a slightly different way. The arcs were different, ships were firing them forwards, and after they would only go in a straight line up to their range. If they didn't hit anything then they would continue in a straight line for another turn possibly hitting something on the way. I've got no idea if that was how an early version of the rules worked but it's not in the book, which to me seems to be a good thing. Too many torps running all over the place and having to track how many rounds they'd been out there for would be quite a fair bit of work in my opinion.
Not sure what I can really say about the fleet lists. The book's got lists for the British, German, Italian, American, Japanese and French fleets along with a few generic merchant vessels. About the only thing I can see about them is that the Italian Navy doesn't have any aircraft but other than that they seem OK.
Being as how I've not played the game from the book yet I can't say what seems unclear other than the turning template. The book describes putting it alongside the ship and turning the bow a number of notches as shown on the template. I kind of feel that a ship should turn around it's middle point as that's where the ship really is. I need to play it again to suss out if this really is an issue or not. In the demo game it felt a bit weird but it all seemed to work OK and the game kept clipping along.
The included historical scenarios are:
Battle of the River Plate
Battle of the Denmark Straight
The Final Battle (end of the Bismarck) (Just noticed that in the book they spell it Bismark missing out the C, the counter sheet has the C on it)
Clash of the Giants (HMS Renown vs. Gneisenau and Scharnhorst)
Arctic Skirmish (Scharnhorst vs. HMS Belfast, Norfolk & Sheffield)
Death of a Giant (Scharnhorst vs. HMS Duke of York, Jamaica, Belfast, Norfolk & Sheffield)
The following battles include a number of destroyers on both sides as well as the named ships.
Prelude to Matapan: Part One (Trento, Bolzana & Trieste vs. HMS Gloucester, Ajax, Perth and Orion))
Prelude to Matapan: Part Two (Trieste, Bolzano, Trento & Vittori Veneto vs. HMS Orion, Ajax, Gloucester & Perth)
Battle of Cape Matapan (Fiume, Zara & Pola vs. HMS Warspite, Barham and Valiant)
Cruiser Action off Guadalcanal (Furutaka, Aoba & Kinugasa vs. San Francisco, Salt Lake City, Helena and Boise)
Bombardment of Guadalcanal (Kirishima, Hiei and Nagara vs. San Francisco, Portland, Helena, Atlanta and Juneau)
Guadalcanal Final (Takao, Sendai, Kirishima, Atago & Nagara vs. Washington and South Dakota).
There are also 6 "generic" scenarios that give set up guides, victory conditions and fleet limits that are then used to fight your own battles.
So that's about it.
About the only other thing that I want to say is that this game feels remarkably "complete" yet remains simple and I'm confident that as with the demo game I can get my friends picking this up very quickly. It doesn't come over as one of those games that lots of additional rules will be published for, something that's going to hook you into having to buy a load of different books to cover it all.
I guess it does feel a bit like a small book for the £20 but as said above I do feel that the book is it. Mongoose won't be making any more money from me buying up their miniatures or supplements. This seems to be their only real source of income for the game and given that I feel happy with the price. Plus I've paid more in the past for games that while "bigger" didn't feel complete and would have cost me a fortune to build up any reasonable miniature collection for. Hell you don't even need miniatures, the counters are great.
