The claim is that the greenish space makes dark objects appear more easily, and I know the “realism/fidelity” claims were clownishly wrong considering the space-fascist future features hand carts (that you have to buy with real world money!) and a star system loaded with 90s malls with hot dog stands, but something about making space itself a soupy greenish is… well…
750 million in revenue and rising is the excuse.
