I mean that outside of exploring the scenery and finding objects and killing the local fauna - environmental interactions - it seems the main source of gameplay on the planets will be these robots, where they're present.
It seems like the structure is basically: galaxy -> solar systems (with space station belonging to particular faction, and a 'police' force that can respond to attacks on the station, miscellaneous ship traffic) -> planets (with resource gathering, fauna, scenery exploring, and some planets having robots protecting fauna).
So when I say 'the same', I mean, it sounds like every planet will have basically the same scope for interaction, plus or minus the robots.
In other words, ideas about cities, or simulated societies at war with each other, and procedural 'stories' on each planet at various levels of a present civilisation that might be present on a planet - these more ambitious ideas that people might have been tempted to think about - aren't going to be explored. It sounds like this a galaxy of very naturalistic planets, where it's 'just' nature and sometimes robots. That's totally understandable from a scope POV, but I do wonder if it could get repetitive. Maybe not, we'll see. (This isn't a problem distinct to NMS, I don't want to give them a hard time about it... it's a big problem for any game that's trying to promise 'a galaxy'...NMS may even represent the state of the art in this, but it may simultaneously display how far we have to go in simulating 'open-world/galaxy' sci-fi in a really deep & broad way).
