Good day,

I have what I believe to be a first run Uncharted Sea's Rule Book.

Can anyone give me a way to identify that this is in fact what I have?

Can anyone tell me the major changes to later prints?

Any and all information would be great.

Thank you,

the latest edition has changes to some shooting rules, the addition of new ships and the rules for fliers and subs.

Anyone know when the new book is coming out?
