The Darken Core could satisfy some with its depressing appeal and may give unchallengeable excuse that some planets are unmistakably relevant, so must we assume else and cant we just accept the way it is...
...Perhaps not, in this time and place, since this is our world and we choose what we see and how we extend our appeal in what direction, and certainly that direction does not have to be limited by its primary image of the cold, brutal, emotionless and death seeking icon of the game, the robot or whatever you might define it as.

Perhaps the other reason, may just be to shadow the surface and work the magic on reducing any  pressure on the server or whatever, if the reason to be so.

My main reason to seek adjustment to the surface is the strain on the eyes if your a full time harvester.
Not only the darkened surface but the 50% of time its night and is ridiculously impossible to see your way around, unlike for fighters... the targets and their definitions are baby fed to the player, providing all the details needed to identify where , who, and how many of  their target(s) there are.
Which in my opinion is unfortunately unfair and unthoughtful.
It is a real health concern for your vision in my honest opinion.

Edit: If for some reason some folks may find an argument reasonable by saying that machines are traceable by the computer and plants are not...
Then i have to say, that the computer your speaking of is of a drastically outdated release and does not by far relate to the game feature were all playing, and please pinch me if we can not beat the prehistoric bio generated sensor owned by the very pet we own, like the dogs sense of smell and ability to identify the very early lung cancer which our very best technology cant, and cats whiskers that pick up vibrations, shapes and distances.
I would imagine if we are working our imagination correctly, lol, we can build a sensor for crying our loud 8D

Please fix, ty
