It should but the way I imagine it would work is that once the content is generated it is saved as fixed. I can't imagine every systems or planet is generated on the fly each time it's visited.
Do you realise how much disk space that would take up if each planet visited had to be saved to disk? No, it would have to be created on the fly.
It does cost money to make games you know ... :rolleyes
Your commenting on something you know nothing about yet.
Admitted that I don't know about planetary landings yet but, as a programmer and PC engineer, I do have some idea of the amount of work involved in having an entire planet to move around on. I also realise the amount of data it would require to do it and, as I have said above, it would have to be generated on the fly each time. This is why I have speculated that you will be confined to the starport or at the very most, only a small area of the planet.
And it doesn't matter how great your algorithm is, you cannot procedurally generate an EXACT copy every time. There will be differences, some significant unless a considerable amount of data is stored for each planet. We have 400 Billion different systems, it's easy to do this on a small scale using exact copy procedural generation with suns and planets but for an entire planet, trees, flora, fauna, coastlines and so on. How many billions of trees can you get on one planet? How much coastline is there? A small bay that was there last week is now suddenly gone because the seed to generate it exactly the same couldn't be stored. How many planets are there we could potentially land on? FD would have to fill their entire offices with disks just to store a fraction of it.
Look at how much data is required to generate the map for Skyrim exactly every time, the textures alone take up 2.6Gb. You can run at a jogging pace from Markarth to Riften in about an hour at most so it's about 10 miles or so. The earth is 24,901 miles in circumference... You really want to go down that path?
Outerra Anteworld has done it for one planet 606Mb on disk currently and that's just for the basic land masses, grass and trees, no rivers or lakes, no roads or cities etc so you could probably easily double that and then some with the extra data to generate the other bits and extra textures etc. That now 1.2Gb and how many core systems alone have planets we could land on? Even if we call it 2,000 (I know there's more than that), that's still over 2Tb of data just for the core systems. The ONLY way it can possibly be done is by duplicating them so, at some point, you are going to see at least two planets that are identical in every way.
Edit: Also Outerra Anteworld doesn't generate it EXACTLY every time.
