Cities, bases, ketchup, catsup.
It makes no difference, giving it a different name changes nothing. Windu is right.
Even some kind of "base" building wouldn't make much sense.
In RoN it made a whole lot of sense. If the new RTS was about specific species(Naboo, Gungans, Wookiees, Sullustans, etc.) trying to colonize a planet or whatever, this would work but the goal of the Republic, Confederacy, Empire and Rebel Alliance is to wipe out the opponent.
