Have other games put together open world and mystery? Yes.

I have a feeling you haven’t played those games otherwise you’d see the similarities.

Yes, I am ABSOLUTELY looking at the mechanics of the game. I’m also looking for innovation. Take something someone tried (maybe it was a big part of their design) and make a full blown out version of it. Pushing the genre in either a new direction or opening one up. Outer wilds did neither. Not to say it wasn’t a good game. That’s not at all what I’m saying. I’m saying outside of those that played it, it will be forgotten. It changed nothing. It came, it endeared, it left.
