Whooo! I couldn't disagree more. They have nice hand made textures and some nice geometry, but their "planetary tech" is really primitive in comparison to what FD are doing. What made you say that?
Their planetary surfaces have more detail, it depends on what you mean by "planetary tech". From a looks standpoint it is far more realistic than what FD have shown so far and to be fair, although very functional from a technical standpoint, looks cartoony by comparison. The perfect combination for me at this point would be FD's implementation with CIG's looks.
On that note, I suspect this is the real reason why we haven't had planets with atmosphere's that we can land on yet. Creating a barren moon with rocks, dust and mountains is one thing. But through in planet life, trees and forests etc, unless you have the tech. to make this look at least semi-realistic
and run at acceptable frame rates, you are going to end up with No Man's Sky and that will break the illusion completely.
I don't think they are there yet but I do look forward to that day greatly.
By comparison, CIG's atmospheres may as well not be there. They have no effect on the ships performance that I can see, the surfaces are still barren and rock strewn, although very nice to look at and they have a passable sky. Other than being able to get out and take your suit off and perhaps not suffocate there seems little point.
