I'm really surprised that neither of the 2019 "Outer" games with similar names showed up in any of your posts: The Outer Worlds and Outer Wilds.
Worlds because if we're talking about Starfield, it's something to consider as a smaller, more compact alternative (although I recently finished a playthrough and there's actually very few comparisons to be made between the two), and Wilds because... well, it's just straight up space archaeology that makes heavy use of travel and planet exploration. Also because it's probably one of the most critically well-received space games.
Something else I wanna throw out there: Heaven's Vault. Nice little narrative game which takes place in space and has quite a calming (even if completely unrealistic) method of space travel.
I did mention it as a smaller, compact alternative, but I maybe wasn't specific enough with regard to the scope of gameplay.
Probably should have specified that I meant Outer Worlds as an alternative to Starfield mainly for people interested in a game set in space with the familiar approach to worldbuilding that Bethesda and Obsidian seem to share a bit, and also because it's not uncommon to hear either of them referred to (maybe a bit unfairly) as "Fallout, but in space".
Then again, most people interested in that would probably already have played it by now (although lots of new Fallout fans this year, so maybe not).
