Well, digging out my notes for Exodus (I'll have to get back to work on it soon
), I've got the following, racial-tech-based minor traits:
MEGASCALAR ENGINEERS
-- several superlarge ship/base hulls; enhanced stellar engineering (ring world /sphere world); Megascalar SY components (huge, but bigger output)
MICROSCALAR ENGINEERS
-- larger unit sizes (fighters, etc). a few combined-effect special-purpose components. Microscalar (smaller, but same output) SY components.
ADVANCED MISSILES
-- weakened nonmissile weapons, but, very enhanced missiles and torpedo weapons, also enhanced antimissile weaponry.
ADVANCED CARRIERS
-- better carrier hulls and fighter hulls. Improved fighter components and launch bays. ?slightly weakened nonfighter weaponry? Improved antifighter weaponry.
PIRATE RACE
-- enhanced ship capture.
Not as big a change as in P&N, but still an option ...
ADAPTIVE TERRAFORMING -or-
ADAPTIVE BIOCHEMISTRY
-- enhanced climatology and atmosphere conVersion (including a starting, *slow* AtmosCon facility?)
