Has it been mentioned if you can visit Earth in the game?
They mentioned you can go to a settlement on Mars, so you can visit the Sol system, but Earth hasn't been mentioned. Either it's off-limits, like in Elite Dangerous where you need a permit to visit, or it's heavily altered, perhaps by nuclear war or climate change so they don't have to recreate all of Earth, or they actually have recreated all of Earth.
There are things to find. Old structures and such. But they are pretty rare and the planet is huge.
I just find it neat to have a base roughly around the same part of the planet as I actually live. Shame it doesn't seem to actually use real heightmap data for anything other than the texture of the planet when in orbit.
There was the day one patch notes that was being mentioned a few days ago. One of the fixes mentions an Earth Landmark. So presumably a unique location you can visit on Earth, one that isn't completely randomly generated.
If Lemmy let me post the picture I wanted then that would show that yes, you can land on Earth. Can be seen in the IGN Starfield Performance Review at 0:35. You'll have to go frame by frame to actually see it.
