I've read through Castles in the Sky and have been sourcing manufactures to build my fleets since.
Since it is miniature agnostic, we have the freedom to bend and break the rules as we please. Take note that not all is set in stone.
The rules themselves play like a few naval wargames I've read with the maneuvering, turning, firing of torpedoes, etc. However what makes it pretty cool is the Command Roll where you get to pool your dice and use it for special orders to tilt the battle (hopefully) in your favor.
Also, there is an altitude factor where a d10 should cover the different levels of elevation. I like d10s :)
Pretty cool artwork of pre-dreadnoughts sailing and dueling and exploding in the sky. Has that watercolour-pastel feel to it. Kind of like looking at a Turner, only flying.
I've been considering Old Glory 1/600 Pre-Dreadnoughts for my capital ships. Although the scales would be off from a Leviathan ship, perhaps a Leviathan "battleship" could be a "cruiser" instead.
Not sure how to make the Old Glory ships fly yet… maybe one could look around for a 3-d artist to freelance a supporting dirigible of sorts.
Hope you guys enjoy it also.
