Outer Wilds has 6dof in your spaceship. It has modestly accurate spaceflight, though everything is on a tiny scale. You can fly from planets, into space, match velocities, etc. It's a game about exploration and mystery without any combat, though.

I like how the games allow the ability to freely move in and out of my ship and the game worlds offer a good amount of exploration. And it might sound silly, but I like being able to perform maintenance on my ship.

Again, this is just my thoughts on it and might not give off the same feelings to others.

That would be weird for Outer Wilds. It's not really a game about figuring out a complex sequence of events that let you get the correct solution to the time loop, the way so many time loop stories are. There are a couple locations that can only be accessed early or late, but those locations only contain information; once you've reached them you have no need to go back on subsequent looks.

And since the game is about exploration, it doesn't really feel repetitive (at least it didn't to me), because you're always looking for something new
