The flow of the menus is a natural sequence of play. With little work, you can adapt it to most every rule set you have, but be aware of several issues. Gunnery is the heart of SB3, as befits a game of the Dreadnought era. However, in its haste to help the gamer, you might be giving up too much control for your tastes. Additionally, SB3 appears to use a linear damage model.
Damage is expressed as a percentage of tonnage, with critical hits thrown in.
That said, that very simplicity of SB3 is what makes it most valuable. In a 1v1 battle, the simplicity is too apparent. I have not found a better set of rules to help you quickly set up a naval battle and resolve it. Final Recommendation Shipbase III belongs in every serious naval wargamers inventory, whether you play miniatures or not. Though not a perfect simulation, it is a wonderful tool to play out battles with.
