The technological styles of each faction are quite different. For instance, during the Iron Sand Desert period, the technology of the Security Corps was a typical hodgepodge; you could see various branded weapons and most of the prosthetic chips on the market. Even that base spaceship was a custom piece from the Mechanical Legion.
In Nightless City, however, an array of neurological chips, internet equipment, and personality implants display that it's a network city.
Including Du Gao Technology, which now has its own style—its mecha being both large and sturdy, along with the various changes in chip technology, truly embodies Mr. G's style.
As for the flying base of Mas Sharpness, the impression it gives Gao Gong is one of rawness.
For example, along the way, Gao Gong saw at least eight kinds of experimental technologies, such as the 'Energy Field Emitter' still in debugging and the 'Ship AI' being upgraded, along with some weapon modules for testing.
