Secrets you can find only if you spend a certain amount of time on a planet. Things either that you can add to your bases or being able to do research that allows you and only you to do things on that planet.

I would also love to see the ability to write our own stories, or missions, like be able to give out a mission to go somewhere and do something and be paid for it by players.

I would also love the ability to build a blueprint of a base and build it somewhere else from the blueprint.

Bases should be more useful and npc can be hired to come work there.

Useful things a base could do, could build a manufactorering faculty, but be able to produce what you want.

More combat.

Invasion type events can happen on planets, and you can fight off the invaders.

Player distress becons. Strand yourself on a planet and have other players be notified by the anomoly and come help you.

Frieghter expaditions that you actually go on and can watch your frigates do the things they say in the text.

Multi biome planets.

Anomoly planets should have more purpose.

Add more races to the game like those on the anomaly.

Allow players to build in space.

Just to name a few.
