I don’t know if this idea was already discussed, but planet landing would create a more immersive enviroment arround the idea of planetary colonization.
But i am not saying about navigate or walk inside the planet… Would be an infinite and useless emptyness.
I mean, instead interacting only with Custom Offices, could be an animation like gate animations, showing your ship entering the atmosphere and landing on a landing pad, or a station, or whatever.
Some new content could be created like a corporation structures that allows player share planet management among others corp members. And of course, this structure can be destroyed and looted by wardecs.
Well, its just an idea that you maybe already had too.
And if this is a bad idea somehow, please ignore.
