3 space stations per team, you can now choose between 3 stations to build, but choose whisely you can have only one starbase on each planet, the buildable stabases and their functions are: Earth allaince, Alliance base (Vanilla starbase) will give you the basic earth alliance units such as fighters, corvettes and light frigates.

The jovan station (Republuc station used in the end of the clone wars) Here you can get all your 'old' and outdated units such as venators and aclamators. old Republic starbase (Station used by the old republic, seen in many other clone wars mods and in the clone wars tv series in the rebellion/ new republic era used as a trade station) you can get all the ships from other Sci-fi series from this base
Black hole pirates, Black hole station (big sphere with several arms seen in a screenshot I posted a week ago) you can get the Black hole pirates basic units from here, Black hole station 2 (updated version of the normal black hole base) here you can the advanced units from the black hole pirates, Colonial starbase (vanilla starbase) here you can get the ships from other Sci-fi series.
in skirmish you just get the basic starbase and the other ones will be buildalble from the contruction satalites.
Active minor factions,'
in GC you also encounter other minor factions who fight back and build units etc. who the factions will be is still undesided.
Skirmish survival mode.
This is a new way to play skirmish battles, your base is located in the center of the map while the enemies are outside the map sending continuesely units into the map attacking your base.
new tech system.
In vanilla foc the rebels get tech by stealing from the empire while the empire must research and the consortium had no tech levels.
In this mod you must you also have a research tab where you can research new units or upgrade existing ones.
New base building system.
In this mod the base building is way different, when you've captured a planet you can only build a comment center wich give you higher credit amount per day, while you build this building you unlock 2 new buildings: the offense center and the defence center. i you build the offense center you unlock the barracks and the light vechile factory while building these you get office acedemies and heavy factories and when building these you get elite academy and advanced factories.
while building the defence center you get all the defensive structures such as turbolasers and shield generators. In skirmish you also start out with the comments center from the comment center you can build offensive center and the defensive center etc.
you can also build special units who can steal enemy ships just drag them to an enemy planet onto the 'steal ship' slot then you get a list of ships that are on the planet (stealing ships is also expensive stealing a ship coxt twice the ships production price, the ai also steals ships from you but you can steal them back.
