Realistic unit building

[Puke]

as for a library of ship designs, you can save a race after having played it for a while, and have all your designs and settings saved with it. if you want that to work with any race, you can enable your ship design minister or turn on the auto-ship-design-whatever and have the AI design them for you. you can then edit the AI design file for your race, or make a 'player design file' and associate it with any races you create.
