I have not yet played Return of the Obra Dinn, but it is always high up on the list when I look for games like Outer Wilds. I'm a huge fan of Outer Wilds, so maybe the recommendation can work in reverse
From what I have heard, the deduction is not as intense as in Obra Dinn, but there is very little hand holding, and the whole game has been brilliantly designed so that it is driven entirely by your natural human curiosity. Once you get through the initial "tutorial" section (probably the roughest part of the game, push through!) the whole game is wide open. See something weird orbiting a distant planet? You can go straight there and start poking around. If you follow the leads that turn up there, you will eventually even figure out what it is, and why it is there. Do that enough and you'll eventually figure out the strange mystery of your home solar system.
Can't recommend it highly enough, but you only get to play it without knowing the secrets once, so go in as blind as you can. It took me 20-30 hours to "solve" the main game, maybe another 20 for the DLC, which is also well worth it
I have put hundreds of hours into RoR2 on PC, love the game. I recently purchased a Switch copy so I could play with a friend of mine who is console-only. Sadly, the port is still in a pretty bad place when I checked last (2-3 weeks ago).
I am not expecting the PC and console experience to be identical by any stretch, but I am talking about basic issues like the music on each stage cutting out after playing for only 10-15 seconds, wonky damage (Beetle Queens absolutely massacring us even on Rainstorm if we touched their projectile splash zones), and all the other miscellaneous issues from the patch like logbook being glitches, unlocks being unpredictable, etc.
I think it could potentially be fixed, but I would give them time to put out a few more bugfix patches before I considered a console purchase
