What would you like to see in an expansion pack

[Nitram Draw]

I would like to see:
The ability to adjust starting techs.
A wider variety of components that do specific things, as in Trachmyr's #13, so that you must adjust throughout the game to different strategies. Not just have bigger Versions of the original items.
An AI that is a little more on the ball, one that analyized the overall game situation better.
Improved AI diplomacy.
Something to make specific systems/planets more valuable than others. A center of your culture if you like whos loss would be devastating to your empire.
Facilities that had an empire wide effect.
A population requirement for each facility to operate at full value and the ability to rank facilities on each planet in order of importance.
