OK, I found my SE3 codes...
Found some more things
Hidden Galaxies - where you couldn't see where any of the systems were located, just where you had explored. How this worked with galaxies with not all warp points connected i don't know
Ship sizes
normal = 100% of normal kt limit per class
enlarged = 120%
Massive = 150%
Starting planets.
You could start each descrete race with a different # of starting planets, and start the random races with yet another # of starting planets
WHY did they get RID of these AWSOME options
