question is...
Is there something to explore? What will be the meaning of exploring?
Just watching beautiful landscapes may be cool for a while but it doesnt have gameplay on its own.
This is something DBOBE has bought up himself numerous times, making the content is the easy part, but making it interesting and worthwhile is the tricky part which is one reason planetary landings will be tackled separately. Indeed, I'd argue most PG in games is just space filling...
Take this for example:
"Aulin – a K7 yellow/orange star
Aulin has a rich, high population high tech and tourist economy (a Federal Corporate State).
Aulin 2, called ‘Nirvana’ is a lush, exotic, verdant outdoor world, rich in indigenous life. A high tech largely biotech and pharmaceutical industry developed initially from exploiting the biological wonders found in the vast equatorial cloud forests. Tourists come to see the incredible beauty of the largely undamaged flora and fauna, vigorously protected by the Aulin Corporation. There is also some farming of high value local produce.
You will already have seen some sneak peeks of the Orbis class of starport; an Orbis, Aulin Enterprise can be found orbiting Nirvana."
So, now imagine with planetary landings we'll be able to seamlessly land on the surface and see the flora and fauna first hand, add more imagination and fly in a Dolphin yacht with your friends to observe things first hand, and maybe go on Safari? I would not be surprised if there is a potential dark side, being able to try and illegally hunt too, smuggling the illicit goods to other star systems for profit...
These are just some of the things we're likely to see.
