I have one mod in which selection of Racial Techs does not merely allow you an otherwise restricted set of technology, but instead determines the predominate type of technology a culture uses. So, with Organics, virtually every facility or component is grown, or is a symbiotic life form designed, domesticated or altered to be utilized by the society. Living ships, which steal blantantly and unabashedly from S_J's concept, are living creatures and have an entirely different set of limitations and advantages then metallurgic constructs.
Most of that is merely cutting and pasting of the data files, being creative with the descriptions, adjusting the variables of cost and effect and stealing cool pictures....
