Stuff like this is almost why I am more excited for the possibilities that future sequels or spiritual successors could deliver.
I imagine a sequel where we get more complex life forms and ecosystems. More complex planetary habitats that perhaps have multiple types of ecosystems in each with more refined animal heiarchys. More refined gameplay mechanics that improve on what worked and change what inevitably doesnt. More complex interiors. Maybe entire alien cities. A more complex space structure with Oort clouds, destruction mechanics like asteroids impacting planets, gas giants and just more diverse types of planets and solar systems.
Not to mention, a more refined graphics engine and polish.
We'll see where Elite Dangerous and Star Citizen get in due time. The developers of both said they want surface gameplay on all their procedurally generated planets in future updates. That's probably years out though.
