It is very difficult to create a Pirate Race without some house rules for the human. The AI could be programmed to a degree but would be difficult to.
To exclude all the colony, mining, research and intel techs would require the entire current tech tree to be made a racial trait. Then each AI would have to be programmed to accept it.
You can design pirate facilities, weapons and such and make them a racial trait. When you choose to play a pirate you would restrict yourself to items on the main tech tree that were not available in the pirate trait.
I would love to play this type of race. It would be a great change from the normal game.
