I really missed something here (it seems everyone already celebrated)'was waiting for the 1.7 update and then suddendly saw this. That's great news!
The espionage might not been updated, anyway I have my own strategy how to deal with and how to take advantage out of it...even if sometimes I wished I could switch it off...but there will be plenty of new stuff.
Unique techs and weapons for each civ will definitively bring a hell of scary challenges and an integrated editor will be fun as well (despite the good work some people here on the forum were investing to build nice working tools).
What I do not understand is the thing with the "Terror Stars"..it's about a new civ or a new event?
Great, thanks a lot for this expansion
