funny..only recently I was scribbling a list of what cargo-space an additional turret should cost on a ship.
I opted for 25 for the first one with every second one for 15 (10 goes to the generator, capable of powering two)
I'd prefer to have weapons drain the energy banks more drastically too:
more weaponsenergy: more drain. then I stopped.
Additional weapons (or weapon power) on the front should be penalised with loss of optional weapon mounts.
additional missilepylons would cost cargospace or sacrifice hull-integrity
A basic system could be set up for choosing first a hull-quality and size.
which would determine how common a hull could be and the general adaptability.
Hightech(2), standard(1), cheap design(0.5) X
specialised(2), adaptable(1), outdated design(0.5). =
base cost hull cost
High tech specialist vessels can hold more powerfull weapons or a great big cargohold while maintaining speed for example, while an cheap outdated design would suffer speed penalties for increasing its cargobay or cargo-room penalties for adding more weaponry or energybanks.
The middleway design: a standard adaptable concept would be in the range of the Cobra MkIII or just below that, as the Cobra is a brilliant design.
As for optional equipment, both extremes suffer penalties. Although this does not penalise the specialist design much, as the most optimal equipment comes as standard.
Older designs do suffer from incompatible hightechnology equipment. However there will be plenty around and spareparts aplenty, so buying one and maintenance is relatively cheap.
The middleroad ship again has acces to most items but does not have many extras fitted as standard, so add these to the basic cost when comparing prices in "Spacer" magazine.
-All these rules are only usable as guidelines for shipdesigners though.
-Also huge ships fall outside the parameters of any reasonable system.
-Designs are only as cool as their quirks, good AND bad.

-Although a nice model and texture help alot too.

-Maybe in future some additional equipment will come scripted at the expense of energy, power or cargospace if fitted. :yay:
