I have something to add - though many people call the current racial technologies quite unbalanced i say it all should be left as it is (i mean in the normal game) because i see that most of the races have one-two useful things, putting it into almost a balance.

Say, the Lighting Ray in Organic Tech Tree is quite the best direct-fire weapon, while the High-Energy Magnifier (recalled the name) is even more powerful than the WMG, which is considered to pack the most punch.
While WMG does 140 damage at range of 8 with rate of 3, the HEM does 110 damage at range of 7 with the rate of 2!!
The Lighting Ray is small and cheap and also the best small weapon i've ever seen for both fighters and troops (same punch, less space, better range).
Also HEM is significantly cheaper than the WMG and puts the another high-damage weapon, the Torpedoes into uselessness.

So here we get almost an balance, i think.
Temporary races get different bonuses aswell, when the Time Burst and Temporal Shifter are nice couple, and tachyon cannon is just nice.
Psychic race get the very best small cannon - Small telekinetic Projector, plus the Mental Flailer and Alliegance Subverter are nice things and Mental Singulatiry Generator packs the best damage at one shot.

Talisman is overpowered indeed, but it adds the religious race what is requied to balance it.

Psychic scanner is cool. so are the enchanced trainings.
Religious are pretty good in defensive style with their shrines, and the temporal space yard & predictor are cool

After all it seems balanced and doesnt need tweaking in the original game. Maybe some new techs, but nothing more.
