I have to admit that I have not been paying as good of attention to the pod casts and forum as I'd like to have so this is not a complaint so much as a request for more information.
Have the tech ages been explained? Like what the end goal for them is?
Right now they seem like arbitrary breaks on research that do nothing other than prevent you from going too far down a tree too early. Nothing else seems to happen when you move into the "next age"
will there be something more or is this it?
