Outer Wilds. (Not to be confused with Outer Worlds which came out around the same time.) While the game is non-violent in that you never actively harm anything, your character will die, a lot, in maybe concerning ways (crushed, out of air, crashed, etc). It also has a story with themes that may be over your kids’ heads. Look up reviews to see more.
What's incredible to me is that the successfully make a game where all of the progress is through information gained while exploring, there are absolutely zero artificial barrier to progress. Once you know the world, you can finish in one play through.
Most games cheat regarding exploration by tying exploration to unlocks in the game. As a huge metroidvania fan, this is can still be amazing.
It's just nearly unbelievable that the team behind Outer Wilds achieved this all through clever construction of the world they build.
On top of this you get a very emotionally compelling narrative and music that instantly gives me chills when I hear it.
Honestly the perfect game.
