No, it's just a Trade Catapult(tm).
140 +50% trade starbases and ~+120 speed - so freighters staying in one place (really they are moving all trade route in one turn). Don't know why, but trade route length in Trade screen is 140 (but a speed bonus is 120). Freighters staying in 138/140 position - so virtually they'are always at the end of the route - better income.
680 constructors, 136.000 production points (+waste), 700 bc/turn maintenance. A real WONDER, not like any in-game ones.
But i can set spending to 100% and taxes to 0% on Gigantic/Abudant with most of the galaxy already conqered.
