I'm playing 2 games as 8472 and Orion. Actually all races have equal colonyships (with EPM=10) except those which belong to general races (EPM=4) and 8472 (EPM=6).

Another issue: it's still too easy to make a selfsufficient ships. Ex.: Dreadnought, 3 nacceles + transwarp drive III + 4 impulse engine V = 15 MP. Supply usage is 420 units per 15 mp. So 4 bussard collectors will easily compensate supply expenses. +2 ramscoops will even provide some redundant supplies. Same situation in low tech game: Frigate, 2 nacelles + warp drive I + 4 impulse engines I = 5 mp. Supply usage is 270 units per 5 mp. It's easy to regenerate them with 4 bussard collectors I (80*4=320).
I think that rule for calculating supply generation values should be: 4 * supplies from maxed bussard collector + 2 * supplies from maxed ramscoop < 420. You only need to find right values for bussard and ramscoop.
