Alpha here a report about my game with the Rage Version 1.0 (I did not yet install Version 1.1 because I didn't want to interfere with the game), full technology:
They are 9. of 15 empires, have war with 3 empires including the number one empire (Ukra-Tal), a non-aggression treaty with one empire (that's me the United Federation of Planets. Well who could resist my diplomatic skills
) and no treaty with the rest. Their ship designs look very good IMO and they construct ships and units like mad and still have enough resources. So I think they perform very well, even if they are only number 9. Having to fight against almost all other empires is quite difficult, so may be they should accept or even propose the NA-treaty a little bit more often.
What you should consider, if you not already included it in your Version 1.1 is a racial trait with special weapons (e.g. crystalline). Their most important problem at the moment in my game are the Ukra-Tal with their organic technology ships!
