Scavenging or Pirate type race
1) Increased chance to find techs from anomalies.
2) Player picks a tier or age of tech and gets a random one from anywhere across that tier or age.
3) Slower research overall. -50% to -100% Research Speed
4) Increased weight to tech trading with other races, great hagglers.
5) Opportunity to Raid, not conquer, enemy planets/research labs for Tech, Cash or Materials to speed up building.
6) Ability to setup outposts rather than planets, uses the dead worlds.
7) No Trading ships instead they get Raiding Ships with the ability to blockade or ambush trade routes for cash, these ships sit on a route or around a planet syphoning money from existing routes and can be destroyed without starting a war.
8) Increased regular colony costs, production and maintenance and colony ship cost +100 to +200%, while outposts are unaffected.
9) +25% Increase to ship speed and range.
10) - Diplomacy, Disliked by most races, especially traders!
11) Optional - Outposts get unique techs to make them harder to find, and harder to destroy, people can just move them, hide them underground, cloak them. Thus many smaller ships hitting an outposts is MUCH better than one bigger one, as they all get a chance of finding it. Smaller ships get more utility, and you'll want at least a few of them around all game.
12) If a minor race, the ability to disable them or enable them in the options. I personally hope all minor races individually get this option, like major races.
I put this in another thread when someone mentioned random tech, then started expanding the idea and realised how much it'd be interesting to either get as a minor race, a full DLC race, or an unlucky mega event that can happen in the game.
What happens to all those leftover ships in the game when you take a planet or destroy a race? They can go pirate. It might also pop up in a galactic mega event, or just be a really different type of race to play, and a use for all those dead worlds. They start off weak but if they expand unchecked they can become a real problem, an infestation you might say! They don't care what relation they are with you, they will still go for your trade routes or raid your colonies for tech or money (but they will prefer to target their enemies of course).
