Yes, I think it would be fun to have one or two of the low level Progenitor techs in ruins for the humans to discover.

As far as the Progenitors themselves, they should have their own facilities and weapons in their tech tree. Some of them we can take directly from SMAC (the Manifolds, Borehole Cluster, Resonance Laser,and Resonance Armor), but we'll need to create much of this ourselves (shields, sensors, resource gathering, research, etc.). Again, I don't think this tree needs to be incredibly intricate, just different (and well balanced with the others).

The other thing I was thinking about was a separate tree for Psionics. Or should we leave it in the main shared tree? If it were a separate racial tech, the Cult, Gaians, and Progenitors would have access, and the others would not (although we might put some generic defense against Psionics - like the empath song - in the shared tree). I'm not sure about this idea. What do you think?
