Starship Building For Fun & Profit (?)

So, I mentioned in my half-assed attempt at a half-assed anniversary post that I had made my own set of rules and a supplement for the same. I'll be quoting the optional rules for building your own starfighter-class ship from scratch below. 

If the players or referee wish to design a custom starfighter, use the tables [below]. Primary attributes start at d4; each upgrade raises that attribute one “step.” Note that STR (weapon) upgrades can be taken more than once, so buying twin laser cannons twice gives you quad cannons. AGI and INT upgrades instead replace the lower-spec part. For calculating costs in game terms, multiply the listed Cost by 2,000 ₢.

I spent a few days tweaking the cost and balancing the various upgrades, to arrive at final totals for scratch-built ships that were playable while still being in the same galaxy as the actual listed cost for those ships (as detailed in official Star Wars RPG books, especially the d20 versions). The ones I already included in the supplement itself (with the serial numbers filed off) are as follows.

 

A/SF-01 B-wing heavy assault starfighter
Scratch-Built Price: 48,000 credits
Legends Price: 220,000 credits (120,000 used)

BTL-S3 Y-wing starfighter

Legends Price: 135,000 credits (60,000 used) 

Lambda-class T-4a shuttle
Scratch-Built Price: 48,000 credits
Legends Price: ~240,000 credits 

RZ-1 A-wing interceptor
Scratch-Built Price: 44,000 credits

T-16 skyhopper

T-65B X-wing starfighter

TIE/sa tactical bomber
Scratch-Built Price: 40,000 credits
Legends Price: 150,000 credits (60,000 used)

TIE Advanced x1
Scratch-Built Price: 48,000 credits
Legends Price: 160,000 credits (65,000 used) 

YT-1300 light freighter (unmodified)
Scratch-Built Price: 56,000 credits
Legends Price: 100,000 credits (25,000 used)

So, what did we learn? Mostly I learned that I need to add a variable to the ship-building rules to account for the number of people that fit on board; that'll likely swell the costs upward to be a little more in line with established Legends. I'll probably work with my partner on this, as fiddling with rules details seems to come naturally to her when it's RPG-related.
