Actually I would say replace more of Freeports, as Jinx said Freelancer vanilla base design is ugly and too simple, we could certainly use more custom bases all around Sirius to break the same design all over it which is kinda stupid considering all the different factions and nations.
It could replace Freeport 11 for start, but it shouldn't stop just on that.
This is great start, and excellent design. And other modellers should concentrate more on bases then bunch of ships.
