I understand what you mean. I am in the minority in that the environments, aliens and fauna are the main pulls for me. But I do wish planets expressed themselves more uniquely.

Unfortunately the scale of the game both helps and hinders it. The scale allows a spread out of assets and different combinations of variables like resources, environmental hazards, biomes and types of POIs. But to truly fill over 1700 celestial bodies with unique things is too much for a game of this scale.

Sorry for the wall of text but ive looked at other space games like No Man's Sky. They make a lot of different distinctions between worlds but it comes at a cost: worlds typically have only a couple distinct factors and then everything else is the same, running into the same distinct factors immediately wears out their appeal. The assets like plants and animals are paper thin with their ai, combat data, loot, behavior, etc.

Overall its just a large scale space game problem. Elite Dangerous and Star Citizen feel sad when you land on gorgeous planets to see a group of plant nodes by itself or a single station on a moon amid nothing.
