[Spaceships] Armor Density

[jacobmuller]

Each segment of the design has equal mass, but volume is a variable, as is surface area. The real numbers would be a pain to work out and not very gameable.
The surface areas for floorplans would suggest armour averages three times the density of non-armour segments, therefore, volume is not the same.

I like Trachmyr's idea (although, based on the surface area required for the given dDR for steel armour, I figure the relative density as 0.7).

Following on from that simple idea (modify SM for targeting and armour), Sphere's should have armour for +1SM. If all other shapes could be said to fall into a "ballpark" surface area; a sphere would fit the diamond:)
And something from old VDS: cheap armour is 1/2 price, -1 SM; Expensive +2cf, +1SM; Advanced +9cf, +2SM.
