If you do like WW1 & 2 battles then it is worth a play with. If you have some skills with PC's you should be able to work out how to add more ships to the ship register. All those AU ships you have seen here in SB could be added to the game to see how they go against 'real' opposition. Great fun.
It is purely surface warfare, aircraft are down to observation off the ships. No carriers in sight.
I've managed to locate a copy. Now all I have to do is figure out how to edit the Bismark file to get the result I need. Then just work out how to create the needed scenario.
