kerpob,
The Little Wars TV guys reviewed these recently, and gave them a good score -
A few friends that still have 1/1200 scale ship collections (which we used to play with on floors or concrete driveways way back when), might be able bring out their dusty old models for this ruleset, since it uses an abstracted grid board that shrinks the sea-space required .
Thinking this system would be fun for game days and conventions - easy play, Captain cards, and if presented with those big old ship models - could be visually fetching too.
