Valuable property

[Marty Ward]

I have a question for the modders.
Is it possible to create a facility, such as a capitol, the would be extremely valuable? By that I mean a facility that, if lost, would have major negative effects on your empire.
I find that there is no strategically important territory in this game. If you lose you Homeworld it's no big deal, unless it's at the very beginning of the game.
Having a critical area that must be defended would add a lot to the game.
