For my Dark Nova 3 mod (avaliable at PBW) I've added 28 new unique ruin techs. They are all racial components and facilites. This makes it possible for a non-organic race, for example, to find organic armour or some other such. The idea was to increase the diversity of ship designs. In fact, the entire point of DN3 mod is increased diversity. The unique racial techs are essentially the same as the racial counterparts, with one slight difference. The unique one's are stronger than lv1 racial, but weaker than lv2. For the most part.
This mod also has the chance for ruins boosted from 3.5% per planet to 10.2% per planet.
The game hasn't begun yet so I'm not sure how it will all pan out. There are 2 spots left if anyone's interested.
The altered ruins are intergrated into the mod but if anyone wants the extract them, feel free.
(and if anyone needs some assistance to extract them you can email me
